Lovely piece of craftmanship but my only reaction apart from being fascinated by it are the background shadows have not been organised to compliment the dark and light areas of the figure ... perhaps too critical but an idea for you to work on. Probably more than can be done with limited lighting, I could well be wrong... you have it across dragon's head but not lower down.
A dragon with fishhead body and mouth or is it a snail ... could spend hours looking at it but must go to bed
The Pern dragons were never like that for sure.
