Like the 3rd the best but it is the least pinup style IMO. The only issue with #3 is the peace sign from girl #2. Takes away from the mood of it all. Also, minus the earing on girl #1.

Dont like the skin processing on #1.

I like #2, whats going on with her rt hand? Also maybe crop a little off the left side. It looks like the carpet ends over there.
