Were you trying to achieve any particular effect, Bill? I like the original as it is clean and well saturated. IMHO:
#2 has a bit of a blue hue to it.
#3 has a bit of a green cast and too much contrast.
#4 has a lot of contrast as well, but I don't mind it with the desaturated background. I like it the best over the edited versions.
P.S.
Poll needs a generic "I like boobs" option. I am now a hypcrite for voting for #'s 1 & 4 yet also the 5th option.
