There are plenty of games nowdays that give you the choice of skin colour. But in this chase I don't think that will be an option. It's not like he choose this palett to be the guidance for every artist/game ect. in the world but just exclusive for this sprite.
Anyhow. This got a bit blown out of proportion and if you feel offended by such a thing, in the future infinitegames , please do one version of each human character sprite with all the possible skintones a person can have...
Back to the character.
Your latest update made it a lot better but I think the hair could use some work. Maby make it less detaild. instead of small strokes of light. put one large with less saturation.
I would also make the facial fetures and shadows in a darker tone. put a a few more colours in it and it will pop out a lot better.
Keep going bud
