I really liked Sam and Tate's design and, if it hadn't been for the placenta separating, I think they would have won. It was clearly the most out there of the alien concepts. I think I just really like Sam and want to see more.
I agree that the winning design was elegant, but it was still a humanoid face - structurally oval with eyes, nose and mouth, and with the full cloak covering everything except the face and hands, who knows what the remainder of the body would look like. I think they won on the close-up work and not the overall concept.
Now that Mr. "I'm going for coffee" has jumped for joy and left, hopefully the disgust level of the contestants and me will calm down.
