The colors are fabulous and gotta love the texture that I can almost feel through the screen. Photo composition makes a great 'abstract' capture of the city with colorful shapes and sizes to engage the eye.
This is very cool, almost 3-D. I'm up in the air about this one, on one hand I like that it is so close up so I can see the artist detail (he is very good). On the other, I think I might like it better with a different perspective maybe backed up a bit to include the building it's on. Without your description I wouldn't have any idea what this was on.
