Hey! I like the little guy!
A few things... from a 2D point of view
I don't know what look you're going for, but seeing as he's a cartoony character, I would suggest more exagerated movements. In the sense that, his spine bends forward a tiny bit before takeoff ;try to bend the spine more than that. I would think it's safe to say that you could even push it until his head is almost touching his belly button
Same with the legs, try to have them drag behind his body almost a full bodie's length behind...
Don't be scared to bend and pull him around, yes, he's a dragon, but not a real one, and he won't bite you if you bend him the wrong way
Good stuff!
