I made a super quick tutorial for someone on Facebook who was struggling with drawing in a 3D space... Well imaginary 3D
Figured I should chuck it up here in case someone else might find it handy.
Always remember your basic construction. Faces are pretty basic shapes too - spheres, cubes, triangle things, putting them all together can be a bit tricky though especially when your brain is telling you there's an ENTIRE FACE THERE D: the key to drawing anything '3D' is to remember to draw what you are seeing, not what you THINK you are seeing. When you draw the mouth, you aren't seeing an entire mouth. You're seeing a partial bit of it, and because the face is not flat, it wraps around.
