Model, no doubt beautiful and sexy, nice touch of the hat to match the essence of the scenery and location for the scope of the picture. Nice placement of the model, and the glance not to sexual for the beautiful place this picture was taken.
Background, maybe a little less out of focus. Something about that hat she is wearing and the look that it creates, would have really blended well to make the scenery be complimented by the model and vice versa.
Overall a winning photo, one I would have been proud to have taken. If the purpose of this picture was to highlight the model, then mission accomplished, but such beauty shouldn't be isolated, but used as an icon to bring beauty to the world around.
Wow, just when I think you've found all the beautiful women there are in Crete, you come up with this. With all due respect to the person who wrote the critique, I think the slightly out of focus background is very much called for. It accenuates Paulina's natural beauty. Love her outfit, and her expression. Yet another winner.
