Approximate Reality

Well, this is the piece I've been working on for my rendering class. Emphasis on creation of shapes in perspective and making them look metallic and reflective. I did far better than I expected to, considering I was sidetracked during the lecture for this assignment.

If anyone sees anything I could improve feel free to let me know. I know there are a lot of mistakes here, but I'm not quite sure exactly what they are.
