I know the guy that made that kanye west sig, alot of the winners from sigoftheweek.com are members of www.nationalsigleague.com Which i was also a member of and a member of the sig crew and graphics crew. IF you visit the site you'll understand what im on about. It also has a Tutorial section made by members so check that out.
I dont go there now as i dont really do graphics any more only to make a sig every now an then when i want one but the national sig league is the best imo. Especially for learning techniques and styles.
KCBLACK, your new sig is your best yet. Heres a tut that my friend made from NSL. Hope it helps. http://www.deviantart.com/deviation/36894807/
