Hey everybody, I have a personal piece I'm working on and would like some C&C.

At this point, I have a cityscape with a balcony over looking the area, 10 colors:

I wanted to play up the focal point of the sun area by having the lines of the buildings lead to there. I hope to include some animation in this when it gets further along which'll bring some more focus to that part.
Anyway I'm totally interested in hearing your thoughts about it and what I can do to improve it.
Thanks a lot!
