brillant, love the sky and detailed background yu did so far, and the fire
only thing i could think of so far is:
-that a part of the wing looks a bit to triangular in comperison with the rest of the wing,
-the neck of the dragon looked better befor your last edit in my opinion
now it doesn't seems as strong and seems to have a strange connection to the body, something seems a bit off , almost like the chest of the dragon ends in the middle of the neck.
- and the cloak of the character seems to be in a way that he couldn't see it almost looks like he's looking inside the hood, could be because he just strated to turn.
