Oops!

It was pointed out that the prompt on the model was in fact garbage for use on Krea2 and that is correct, I didn't update/add that when I uploaded the Krea2 version. Here is a better prompt for the Krea2 users:

A glamour photography photo of a beautiful, slim woman from the side.  The framing of the photo should include her entire body.  She is lying on her back, she is looking at the viewer with parted lips.  She has long brown hair, striking cheekbones, expressive brown eyes, elegant eyeliner, expertly applied brown eyeshadow, long eyelashes, freckles, and pink lips.

She is toned and fit.  She is wearing a black bikini, she is pulling the swimsuit up with her hips off the floor, she has raised_hips.  Her knees are up, she is on her toes.  She has smooth flawless skin.  High contrast, shallow depth of field. She is a sexy adult woman in her 20s.  The background is a luxury hotel pool. the lighting is bright daylight, casting dramatic shadows that emphasize her anatomy.  

I don't claim to be a master of prompting, or a master of Krea2, but that prompt will definitely work better than the PonyXL prompt above.
