@dalron: cool tips on the shading!
@kaisaki1342: If your model is intended to take inspiration from modern “kawaii” / cute archetypes, I think you need to put a much smaller nose and a smaller mouth with less protruding lips, basically you almost have to just hint at them, without them making hard shadows (especially from below). Try increasing the space between both eyes, while keeping them large. Eyelashes are important to achieve a feminine look. Also avoid making facial bones and muscles in general too visible through shadows in normal light (unless yours is intended to be a muscular girl), again realism is not very important here, you need to achieve a “clean”, “pure” look.

It helps a lot to take real PVC models/sculpts of anime/manga character as reference:
This picture is very small in resolution, but it’s just an example. Of course, high resolution photos are better and will help you understand how to recreate similar characters in 3D.
