I'm always a fan of dragon people, even though personally I thought it was a snake until I read the tags, and this picture is pretty well done. The background works for the most part until it hits around the bottom areas where it kind of blends in with the tail but it's still good. To me the lack of details for the gems kind of works out in the end even though I originally thought they were flower petals.
Also just curious as to what the details in the tail would have been, I honestly can't think of how it could be more detailed at the moment.
