I'm all for looking at PSD's, but just make sure all your doing is looking. Don't drag layers from one to the other. I'm not saying you did, but some of them look like you might have.
Anyways, all this lacks is lighting.
Don't like the colouring, and it looks too dark, and seems as though there is too much threshold man.
Not your best.
Reduce the height of your sigs a bit as well.
