The issue for someone at your point in all of this isn't learning Maya, it's learning about modeling, animation, lighting, and so on.

Drawing classes may be an excellent step but you have to ask what you want to *do* with your work. If you were pursuing lighting, a photography class might be a good place to start, as much of the 3D technology attempts to simulate, to one extent or another, photography.

Otherwise, learn whatever you can and don't make the mistake of thinking that knowing what buttons to push is enough!!
