Reason of edit:Editted and uploaded in tinypic as @The Reaper mentioned i didnt removed the attachment cause i dont know xD

First off, why don't you uppload it to a Image hosting site, so we can see the full rez?
and it looked kinda good.. but you can barely judge cause it's so small.
E.X like this



Tinypic is a good image hosting provider.

It needs more work on the depth because it kind of looks a little bit too flat.
