I have to say when I saw the title of the thread, I was worried, but that dragon shape is far more naturalistic and organic than I thought it would be! At the moment I prefer the first map, but I think that is mostly due to the fact it has far more texturing and detail that the second. You want to dull the contrast a tiny bit on that first one if I were you and the second one seems to go the other way. You can still get that artistic feel for it whilst bringing the land a bit more to life with details. Just check out a few world maps on the guild and I'm sure you'll see what I mean.
Anyway, great going on uploading your first map and I look forwards to seeing this develop!
