I’m probably a bit late but I think the part that look,s off is that the torso looks big compared to the head and the legs and shorter than normal! Ah also I noticed on your other artwork you don’t include rim light and I think adding it would look more realistic.

One more thing uh I think that having shapes of shadows and light would work well as well since I notice you mainly use gradients from the lineart and it seems restrictive to only work from the lines (I hope this made sense) gradients are amazing tho so keep using em!

Ah sorry if it sounds harsh it’s just art is so good already I have to dig deep to find stuff ahhhh I hope I don’t come across as condescending eee
