it seems organic, the flashes of bright colour seem like catches of light, and the all seems to fade in a murky depth of some sort...I think I know what KhaoticStorM meant about the negative space though. Perhaps if there was just a little more going on at the bottom, perhaps to give a sense of either a floor or something leading to a floor. I don't know. To be honest, I like it.
I enjoy the atmosphere in this one man. However, I think it leaves me unsatisfied because of all the dark negative space, I think it would have solved it if the focus was moved down towards the bottom since our eyes usually start looking at a piece from top to bottom, it makes much more sense to have the focus on the bottom. As of now, I see the eye candy and when my eyes scroll down I'm disappointed only to find that theres nothing more.
