awe, i'm not saying your sigs are bad, i'm saying our styles of signatures are completely different from each other and would take my signature shop in a less serious direction. you have a corel painter feel and mine have a adobe illustrator feel to them.
in addition, i don't believe i'm in any position to place judgment on your skills because, i myself am not well established yet, you are still learning Photoshop, and try to stay neutral in almost all cases.
