Here is something I just started, I am not sure if it is done or still needs some more time. It is supposed to be an abstract skyline. What do you think? Here is what I have so far.
I know these are very simple shapes, but my instant impression was of the very interesting bright light you can find shining off of tall buildings like these. I've been thinking about how to convey that in a drawing myself. You get a bit of that feeling across.
