It's incredible! A very minimalist art piece. It's so simple yet complex in it's chaotic refinement. I can't wait to see your next pic. maybe next time you should do the view inside a bottomless pit, or what a blind man sees.
Hey impreza, I'm not gonna say it's good but just keep practicing and it will start to look better and better. Check out the drawn stuff in the Photography and Graphics. I'm one of the peons around here trying to draw better as well so I hope you don't feel bad about my comments. If you need help as anyone here and feel free to ask me stuff as well.
edit: Also, if your are comfortable with 3/4 view stay with one relative shape and practice getting the perspective then you can start doing shapes.
