Those are some VERY well done legs. They're well articulated and have this liveliness about them, like they're just waiting to get to stepping!

Watch with the "over-round-ness" of inflation Draco. That bulge at the base of the tail is terribly awkward as are the weirdly square shoulders you have on the front view. The back view is beautiful! That anatomy is great. I know it's inflation art and all but looking from the very natural lines and shape of the body to the artificially round and unnaturalness of the head is off-putting. You could have conveyed the rubbery-ness of the character using shading. Alternatively you could have played around with transparency to show that it's effectively an animate pool toy.

As it is, it just look like an anatomy sketch with some odd unnatural bits that don't totally fit the mold. Just a few ideas. It's a very well done piece!
