You can go into architectural visualization. In any of the fields, developing your art technique and studying are key. But I think, like "CAD", 3D modeling is a tool for something bigger you will do. Maybe you will be a creative person like John Lasseter, or maybe you will be an architect or engineer. It has to be MORE than just doing the technical or fun stuff, or you may end up just a CAD jockey with wings. Find your passion to use your skills on.
but...VERY cool work here. I look forward to seeing more! Thanks for posting!
