Building [Shape+Shadows]

[Imago]

Well i'm working on my own little solo project at the moment but the point is, I need some opinions on the image below. Its obviously just an outline with a color slapped on but i was wondering if the whole light source looks okay.


Btw.. this is possibly the first time i've tried to make something isometric [that I can think of right now] but don't let that influence your opinion, please don't  :roll:.
