do you know the works of Eugene Carriere?
Nice work. On the first one, a bit more core shadow and reflect light in the mass shadow will help improve luminosity. It has a photographic effect happening where the shadow is overly simplified at the moment and the one eye is totally lost in that. The second one is nice and I think a bit more opaque light and paint strokes in the light would strengthen it even more. Check out how carriere picks up his paint thickness in the light. See what I mean?
