This piece works a whole lot better with your style, from what I've seen on your page. I would say that unless you intend to work with other color schemes, you should stick to red, black, and white. Not only that, but the sort of grim tone that this has also complements it. Make sure to keep your line work as crisp as possible so that it doesn't take away from the work, unless you're choosing to give it a more "stylized" look, like a pen drawing or sketchy look. Overall I enjoy this, and say keep at it! Good job!
