Between this one and the wiz sig, I can see you are improving! Much better than what I have seen in the past. I would start looking into creating depth. Once you start incorporating that effectively I think it would completely change your sigs look and give it more life. EDIT: Forgot to mention that this signature has some depth in it. I think if you worked on the lighting it would help out alot.
Thanks DTA, i have been searching for active sites to try and enhance my techniques, but unfourtantly all i can find is dead forums with a bunch of tutorials. I just read a tutorial on using gradient maps and brushes for a lighting and i am going to try and look into depth. Lol kirbir i dont know what to say to that.
