The Dark Lords true form

this is definatly an improvement from my first attempt drawing the dark lord's second form, in my book. I wanted to give him a mixed look of oil and obsidian textured scaly skin and I think I hit the bull's eye ^^ and another thing, I wanted to give his form a mix between a bull, snake, and of course dragon and I really hope I blended the three different animals well. So what do you think? ^,^
