The picture seems brighter in her torso area. Try fixing that to maintain the same brightness as the original. Every other color looks pretty good, but the purple fingernails aren't really in my favor.
I added a light white gradient over for lighting, couldn't decide whether to keep it or leave it, I'll take it out and post a v2 in a sec edit: Oh wow, I just noticed a major mistake, but ill fix it tomorrow, first one to notice it gets nothing.
I don't get what's so cool about this colorizing ****. You just fill in some colors and then hit like overlay. You should try like actually repainting her or something.
