It looks like you’ve used a bunch of transparency to achieve some of the colors, which gets a bit messy in the mouth, jaggy in the nose, and distracting in the ear. Transparency and blending are great tools to find new tones, but with pixel art, we generally consider these opportunities to improve clusters and color usage, rather than scatter and splatter mixed shades. I think you could keep all the nice rosiness while cutting your color count in half or better, not just for the sake of it, but because the piece itself would be necessarily refined along the way.
because of the layers that l did in overlapping to get shade, this one came out so much of colors
Watch out for duplicate colors, you managed to get a 105 here!
105 colors is too much and not in the spirit of pixel art.
The art piece itself looks great though.
