I wish you hadn't cut off the shadows in the far left corner! That said the repetition of the levels is nice thogh i dont like that the one building seems to melt into the second.
Not bad. I think I would have liked not to see the building behind it though. I know, you can't move it, but it would have been stronger since its such a slight angle that you took. - 6
The juxtraposition of the buildings is interesting and the blue sky nice and clean. I would have liked to see more repetition in the image and use of the shadows.
