/ic/ - Artwork/Critique

first time trying out this sort of rendering and lighting after doing lineart + flat colors for ages, any thoughts? i kinda signified where i want the highlights to be, but i honestly think i should push it a bit further like how i did the face (which was on a complete whim desu) but i genuinely can't think of where the light should go and how harsh i should make it
also this looks way more washed out on my computer than it does on my tablet, could someone just tell me how it looks like on their screen? is it readable or does it need more contrast?
