Fuck'n weird...
Thats... random. A little messy, but some parts were amusing... vaguely. Also the music was just white noise to me and thats saying sometyhing as metal is usually my thing. I agree about the backgrounds, convention says you make the scene then fill in the details. Your flash need slight refinement but some of the more 'realistic' characters were quite well drawn. Keep learning your trade, and learn from your mistakes.
