Those painted cylinders and cubes look pretty slick! Perhaps try some more complicated objects? As for your faces, the b&w face in #25 looks more solid than the latest face. I see the neck shadow and hair highlights but the face looks flat. Try to apply the stronger value scheme of your greyscale portraits to the color ones. Also remember the shadow cast by the hair. But first I think you should do more b&w studies from color- with varying lighting directions.
