This actually looks nice. Why haven't this gotten any replies yet?
The only thing I'd like to pick on is that you should use more references, and make the yellow more... yellow?
I'm not sure how to explain how, but try finding the base color of what you're recoloring. Then replace the base color with yellow, which is your new base color. Then you find shades from there.
I guess I'd give it a 9/10.
You seem to know how to recolor, although the yellow should be brighter and you need to use references when drawing characters you don't know the exact design for.
Yeah, and here is a reference pic for Neru, found on google. You may use it for future fanart, I guess?
