Nice. I guess they're still WIP? (or maybe you're aiming for some sort of style?)
I must say that it's very good, despite being incomplete. The pink metal thing shows some nice reflective surfaces, but that section at the top-left of its "head" seems a bit off, and the midtone next to one of the highlights on the edge of its "head", I believe, should be replaced with the next darkest pink.
Teh face is teh awesome.
