You need to pick thicknesses for those areas and make sure the lineart thickness matches throughout. Combined with that, you need to make sure that you minimize nodes, and that you make sure the nodes and handles are parallel at all times in order to create good consistency. You also ended the finger lines as well as some of the hair/clothing with either blunt square ends, or rounded ends. Make those areas end with a single sharp node with independent handles.
