Jack(please let it be rated in the SPAM forum next time, or add it to your showcase, in the future, kthnxbi ;) )
^That. Next time open up your own showcase so you can post all of your work there and not just one sig at a time, otherwise there's a thread in the spam forum for that
Anywho, The sig ain't bad at all, pretty nifty. I like the swirls. I'm not crazy about Sonic's thumb, nor his hair in the back, but all in all pretty nice.
