Onyx Dragon's Eye

I called this "A Silver Dragon's Eye" but that was because it was all I could think of at the time and it isn't really a silver dragon's eye cause then the scales would all be silver and there would not be any black
So this is my Character Onyx, he really has a rather minor part but I painted this before I came up with him and it inspired me to creat him. So that's that. And I've said enough cause I'm talking too much
