Color and face edit. Also, reduced the color count to 20, plus transparency.

Contrast! Also, I don't think you need to be dithering this NEARLY as much. Some is perfectly fine, but the single pixel noise especially just doesn't work. Moreover, it seems unlikely that someone who (presumably) spends so much time outside would have such pale skin....
I don't mean to be harsh, but I liked the original concept design a lot better. With her tan skin and only wearing the loincloth and the mushroom cap, it looked like she belonged to a mystical society that is deeply integrated with nature. Now that the mushroom cap matches her 2-piece bathing suit ensemble, It seems like a silly costume. I do like the tattoo though; I think it is a nice addition. However, the seemingly pampered hair just pulls her further away from (at least
my impression of) the original concept.
Not like the current design is
bad at all; I just liked the original so much I thought it was worth noting.
