I like the first Tracy sig, the other one makes him look too blue >>; So I give them both an 8/10
Now the Vince sig has an cool outline that looks good in amost any sig and it's bg is is pretty good though there is too much white a.k.a Empty space let the bg pic be seen and not invisible. So I give the Vince one an 7/10 Cool works Tan
