Would make an awesome poster!
I really like this! The style,effect and colors are diffrent in a good way and that dragon with the blood coming out of his mouth is just epic :) The only little thing I would suggest is maybe change the color of the border to a blue or a dark red, the yellow doesnt go with the rest of it in my opinion but thats just a little nitpick that doesnt really take away from it. Awesome job dude!
