Creation of game ready Character model (Chibi)

I had this character made previously but it does not match the quality of the previous character I had made, I’m looking for it to be remade to similar quality of the male character I’ve attached. You will see the difference in quality from the images attached. Overall the scale needs to be the same and the overall texture and model quality needs to match the male character.
More work likely to follow in the form of 2 other characters.
