Well after receiving others criticism, I started to see all the flaws in the painting so far and I started over, keeping only the head, trying to fix the old one was just becoming hopeless.
Went with an entirely different concept, and looking at it now, I can see that this pose ALSO has some major issues which I'll try to fix up, I think so far at least that it looks much more promising than the previous effort.
I still got much more to do (like adding in the sword, proving to be difficult like last time) but I wanted to go ahead and get some criticism.
Concept is supposed to be that it's from the perspective of a wounded dragon
Here's a detail shot

And full composition

Thanks again everyone, I really want to get this one looking as good as possible to be the best of my artwork to go into my portfolio, so it's kind of stressful working on it! But please mention any problems you see with it, so I can get it to look as good as it can.
Thanks
