Until this point, we have learned a lot from the lessons and from the two illustration projects, which are the skull project and the three on a hill project. Before we wrap up this section, I want to show you some of the benefits of using our non destructive workflow. The first benefit is the flexibility to recolor the illustration. For example, let's say we want to make a winter version of this illustration, we can do recoloring by either targeting our base color layers, or you can also have an additional layer four that for now, we will go with just using our existing base color layer. Let's be a snow color. It should be very near to white color.

Okay, now if we just fill the layer using shift backspace shortcut, we can see we just break the coloration parameters that we have blocked everything in a background layer. Let's undo this force. For this to work properly, we need to turn on the alpha lock in here, so the editing process will be constrained to the current layers alpha. Now if we just brush out like this, we can see the color on go outside the existing radian. To quickly colorize the whole layer, we can do shift backspace again, like before, as you can see, the field color command will respect the alpha lock option. Next, I want to revise the leaves color down here because usually snows built up on the top areas of objects and not so much at the bottom areas.

Let's speak a darker blue collar but slightly towards the green color and just brush like this Okay, Now you may still see these greenish colors in here. This is because we have the detail layer on top of the base color layer, which is great. Next, we want to change the color of the tree trunk to be less saturated so it fits more with the new environment. The next benefit of our workflow is the ability to add custom details as needed without the need to redo the shading. For this example, let's try to add snows stacking on several areas around the tree. We can do this using the recoloring technique we discussed previously which basically just using the base color layer.

Let me just show you this real quick. Pick the previous snow color from the color history and just use the airbrush preset to add the snow color Essentially, it is a recovering technique. Okay, what I really want to discuss now is creating custom detail layer. Why do we need this? Well, if you look closely, our three has this grout or bark lines inside the local shading layer, which essentially block the base color layer. If we want to add a snow that is actually sit on top of the bark lines, then we need to create a new paint layer on top of the local shading layer.

But because it will be below the global shading layer, it will still receive shadows just as we expect it to be. Let's name this layer snow. Because this layer is a custom detail layer that contains only snow. Turn on alpha inheritance, but lift the Blending Mode to Normal next week can use the airbrush preset to add the snow color like this. Or we can use custom brush that looks more like a snow pile or snow spreads. Let's pick this one for example.

And just add the snow like this. As you can see, by using our workflow, we can easily create many different variations from a single artwork. Okay guys, so this is what we have after tweaking our original illustration. The third example of our workflow benefits is that we can easily change the lighting in our illustration. Let's see, we want to have additional light source coming from the left side of our tree. We want to be drawing the light source to save time.

Just imagine that we have a campfire or other burning objects of the land. aside, we do this intentionally to create a backlight for our 3d object. If you don't know what backlight is, brake light is a spatial light source that we intentionally place on dark areas to help communicate our objects shape or our silhouette, or just adding mode to the illustration. For this, because backlight is actually a light color, we need a layer with a screen blending mode. If you previously created highlight layer, you can draw directly on that layer if you want to. But I usually separate basic highlights layer from other physical effect type lights, such as backlights.

So now I will create a new layer on top of the shading layer, rename it to V for a peaceful effect. Turn on alpha inheritance and change the Blending Mode to Screen. Next, let's speak strong orange color and add the color either using the airbrush preset directly or by using selection first to have greater control of it. I'll speed up the video because you should already understand all of these techniques by now. The next example is adding rim lights. rim lights are just like brake lights, but they are more General in where we add them, we can add rim lights to strengthen objects silhouette anywhere as we see fit.

Now, you might be wondering, will rim light make our objects look too fake or not real estate? The answer is yes, if you overdo it, but if you just use it at the right dose, it will help you bring the main object in your drawing to focus. This is how professionals in photography and cinematography use rim lights and brake lights. The process of adding green lights is basically the same with adding backlights, and we also use the same v layer for this. So I'll just speed up the video for now. Okay guys, we finally finished adding visual effect lightnings which are the brake lights and the rim lights.

This is before and this is after. The next and the last example is overlaying our initial sketch drawing on top of our final illustration. If you remember that previously we reduce the opacity of the sketch layer 220 percent. That is why the sketch lines are very subtle now You can play around with this value depending on your taste or your art style. For example, you can drag this all the way to zero if you like playing rolling, or you can go all the way to 100% for example, if you like this kind of art style, personally, I don't like having these lines at all. But for now, I will go with 50% This will make it looks more like a children's storybook art style, but I think 40% will be better.

Okay guys, so this is the final result of our illustration variation. I hope you learned a lot from this lesson and starting to see why having a non destructive workflow is very beneficial. And in certain cases, it may be even crucial. For example, if you are creating a certain game asset and you need a lot of different variations of asset quickly
