And here comes the furry war, even though it was specified to not be a furry seeing as it's a plain old dragon, just, on its hind legs. It looks fine to me, but since dragons are mythical creatures, I can't really give you any advice on what to study aside from look at how the skin of many reptiles looks, if you do color and shade it, I would base it off of some kind of reptillian animal. It's really nice though. I have a feeling this topic will, sadly, either get little attention or a whole bunch of negative attention, just because of how it's posed. :C
Good job though man. :3
