They are all very nice. However, I would prefer a different mix:
– the body of the third (alluring muscles :P),
– the palms of the first,
– nose of the first OR more like the one you gave your male dwarves,
– slightly smaller feet to keep the proportions.
I voted for the third, because it is the closest. Oh, and a way to make smaller – if any – fangs would be wonderful. Perhaps somebody would enjoy human ears too? I certainly would :).
