Looking for input on my drawing

Well, depends always on what you want to make the center of the image. If you want the buccanner to be the center, and want the background to be improved, i'd have a tip for you. Know the Dragon Canyon background? Not only it has some amazingly deep colours, but it has lightnings falling from the sky. I'd suggest doing them, as well as abusing the black and white effect, and to give more attention to the char, do a bright outline for the shadow and lightning effect.

Since it really won't help with just words, i've done that as an example for you. This is how i can see that it can be improved :O
