Rendering Curved Surfaces

We watched a video about shading curved surfaces. In the video, we learnt about different types of light and shadow, such as highlights, centre light, reflected light, half tone, form shadow, core shadow and occlusion shadow. We were given a lineart to practice shading curved surfaces. 

Here I tried to work out where the light source would be coming from by laying down the kind of shadows and lights in the video. 


Next I tried to bring all the shadows together to look more realistic.


Then I cleaned up the edges and the areas where the original artist used cross hatching to shade, such as the legs.


Finally, on a new layer set to multiply on top of everything else, I added some colour. I used a yellow-green base, added some lighter green near the lighter areas and darker yellows and browns in the shadows. On a separate layer I added the highlight.

This is the final image.


I struggled a lot with this assignment because unlike in the video, which uses an egg, the creature has a lot of skin folds and is not a smooth surface. I found it hard to deal with the shadows and determine where the correct ones needed to be. I think the shadow on the floor is not convincing enough, so next time I will spend more time there. Also, the colour is a bit dark. Next time, I will use the background colour as the mid tone and add lighter greys where the light is reflecting. This should allow the painting to look less muddy.
