Your pieces are becoming quite abstract and interesting santino. I like this one, its all the interaction of shadows, not actually "real". You might want to crop a tiny bit off the top since the stuff in the top right and left corners is slightly distracting.
This is interesting.
It is not quite abstract and yet it is abstract. And you play with shapes and lines, and all only as shadows ... extremely cool concept. I do agree with Darin on the top righthand corner. Just that tiny bit, that dot there, might want to "go".
