Good work! I will give you pros first.
Pros: I like the way the body is positioned, the markings and claws look really good.
Cons: When drawing the main structure for dragons wings you should make it a little more skinny but not skiny enough to make the wing look like it will break when flying. The head could be positioned a little differently and the top part of the leg should be a little more refined.
I like this picture because one i like zolt. and the picture is colored well. The position of the wings was good and the length of the entire body is good.
You are doing really well!
