New to environments

[niku]

I don't do a lot of environments, but I'm trying to do more. This was for a class on perspective that I'm taking, and after doing some work on it after getting feedback from turning it in, and hopefully fixing some of the more basic issues, I'd really like to hear from people regarding what I can do to make it better. The assignment was to use line so that it's easy to read, but I may go back later and render it.

Thanks in advance for any feedback you can give.
