Shadow wolf: the eyes take away from the rest of the piece, they look flat. Also, shading on the torso doesn't quite fit with the one on the legs (the legs look better) and head. I'd tweak that, changing the highlights further up the torso and adding an extra middle shade between lightest and midtone.
Blick, you really should finish that, for the sake of mankind. Her skin is a bit low on contrast, if possible try to work that with the palette.
Badassbill: oh wow. Looking good, good luck with that huge thing.
Sohashu: the shading on the tail and lower leg shouldn't be gradients of the upper leg. Your shading should try to define each of the parts of the dragon separately, as lighting hits these surfaces in different manners and angles. And maybe a bit less saturation would look nice.
Something i'll be colouring ocasionally, might as well share.
