The one on the right is fabulous, but although the one on the left is good, I woul work on the shading. I am working on shading myself. It was hard for me to get the hang of at first. All in all I love the drawing. I don't see what you mean by it not looking 3D. I think that part is very good. I think that if you see a problem with it not looking 3D fixing the shading would fix the problem that you see.
