another dragon one,c/c please...

It's not too bad, but too much going on, and the dragon is hard to catch at first. Try to bring out the dragon more, and create more of a natural flow going along in the signature. Also, maybe try a bigger size for your signatures?

too small, i didn't recognize what i was until you said it was a dragon.

Expand on a large canvas, you can always re-size/scale
