Patience!! Sometimes whole days go by without a comment ...
The textures in the last one are great. The second is really hypnotic - printed really large it might be dangerous. I also like the composition and color in #1. #s 3 and 4 don't do that much for me. I think 3 is a little overexposed.
Very nice! My favorite of the bunch is #5. I think its a really creative perspective. All it needs I feel is a little touching up to really make it pop and emphasize all the lines and shapes. This is kind of the way I saw it, I hope you don't mind.
