I'll say this first: It's better than anything I could do from scratch. I'm terrific at altering what's already there, but making something from nothing is a concept with unfortunately eludes me. Now I've seen some pretty damned good artists in my time, and I appreciate artists more than most (of any calibur) simply because I envy them so. You show more promise than ALOT of artists I've seen online, and I'm gonna tell you now there are some people that I've said "they should just stop even trying" but you have some real potential.
Onto actual content of the picture, I can say this, the details are perfect as far as I can see. The dragon face on his shoulder pad looks great, and the details on the mask are perfectly placed. HOWEVER, there is some bad news...the dragon is entirely wrong, in pretty much all ways. His extremities are very ill proportioned and he isn't particularly symetrical in the head region.
