They look like mean ass models, nicely painted; I am also a fan of the colours you used.
Main point I would offer on the C&C would just be they could be tidied up a bit in places, but that really depends on how long you want to spend painting them or whether you want a nicely turned out army to play with.
Maybe some smoother blending, but I like your style to be honest. I can imagine the full army would look great!
