Well, it's not THAT bad! Just a little bit choppy. And the stock is really well merged in with the effects... You gonna try again?
Ouch... Bring out the stock more a bit. Lighten it up and add some more colors with Gradients and Photo Filters, etc.. I like the texture, but the rest of the sig makes it monotone and unattractive. Keep working on it.
I think you should do something with the colour. It's just like one colour,(like Roxas said.) It looks a little boring, sorry misty:)
