Well, it's a very nice start, the shading looks nice. I spose you could say you're drawing in the style of ran, but there are some differences. I'd say definately continue, I can see it has some great potential in there to be a nice sig :) Also, just a quick ps, just because you're drawing in the style of something doesn't mean you're stealing their style, it just means your taking their way of drawing/painting and putting your unique spin on things :)
