It's very nice. I think it needs some more contrast. There doesn't seem to be anything outwardly eyecatching - maybe something below the face? Extension of the body?
Add a penis, that would catch the attention of a few members here *cough* Stephen *cough cough* But yeah its nice, keep up the good work! Maybe you could make one for me?
Just to add on to what I said earlier, the right side of the tag seems to be very dark - perhaps a bit too dark.
seconded. The signature is great, I really can't find any ways to improve it. It's got great feeling.
