The head is the best part of this set.Those white details make it look good. Maybe you could add some shading and highlights to make that black part being deeper than those golden plates. The hands are lookin ok too. The white lines look pretty random on them though. Torso textures fit the set very well. The thighs, legs and feet are... simple. They look too different from the head. Maybe you could add more dark areas and more white to them.
It looks still ok.
