I still don't like the texture (which I know is still temporary), but this is an improvement.

Are you aiming for realism at all here? If it's going to be more cartoony (for lack of a better term) then your wings are fine, but if you want this to be realistic, then you need MUCH bigger wings. I guess it also depends on the effect you want. Generally if the dragon is supposed to be "bad" (i.e. create a sense of doom) then you want to go for more realism. If he's more "good" (think of films like "dragonheart" where the dragon is the good guy) then slightly less realism and a more personified character would give you a better effect.

Something isn't right about the tail... for one I would make the taper closer to the end there, but there's something else... Perhaps it's just attached too high.
