#3 and #6 definitely take the cake! I would say #6 has almost everything in it that I like in a head shot photo...gorgeous lady, awesome eye contact, tight cropping, and who couldn't like nice cleavage. The only thing that seems a bit amiss in the photo is that her right breast seems to be dwarfing the left one perhaps because of her breast being up against something. This gives the impression of very lopsided, or one-sided, cleavage, if that makes sense. Typically I would expect to see the curvature of the top of both breasts in the photo but can only see it from the right side. Nevertheless, those eyes and that incredible smile are nothing less than stunning. Her smile is infectious and articulates an easiness and comfort with her surroundings.
Thanks for sharing!!
