You know what,
I'm going to make you a favorite. I just went through your art pieces, and okay, I didn't write a little review on all of them but this one I find to be worthy of it. It's simply brilliant and I'm not as to how you don't have a gallery somewhere. Of course, if you do, then it seems I'm just living under a rock.
Anyway, really well done on this, but I agree with XwaynecoltX you could make them look more like bars. But I did also think that maybe, that was intended as a view on insanity, you know, out of place proportions and so on. That sort of thing.
Either way, brilliant :)
