After closely looking at all six images from a photo editor's perspective, yep, I've held that job before, the closest one to what I like would be #1.
The one you posted is cool but I think it makes her face long, though I love her expression for "fun." Also, her
left leg ends at her knee cap. In fact they all do, with two exceptions all but this one shows a bit of the foot that looks, well, just sticking out there like a sore thumb, in fact it maybe her big toe. I'd prefer to see the legs, though from a profile angle. #2 is a "Page 3" girl type of pose so the legs are different and doesn't pertain to the last comments.
What do I like about #1, her face, the hair takes the roundness out as it goes across it, plus it doesn't look long like in the one you chose to post. However, it's a sexier expression, but if you want a fun one, then go with the one you posted.
On another note, what lens did you use? I would have went with the longest tele you could in that room cuz the tiki's do nothing for me, but if you have to have them, compress them more and throw them out of focus. The human eye will always go to the "lightest" part of an image and the flames are specular bright. I noticed in the one you chose you burned them down a bit as they look muddy. If you have to have them, they look better in #1, though I think they are overkill. I would have rather had a campfire in front of her like you see in so many cliche Maxim
photos, though just glowing and not roaring.
Now, my apologies for being a bit harsh, but I'll tell you why--you're a damn good photographer, and I learned a long time ago, sugar-coat the up and coming
guys so they never get discouraged and stick with photography, but on someone that is good at what they do, be firm. Your work has tons of potential for publication. It shows you are into "detail" with this shot. The shot you posted is publishable.
With your background in cinemaphotography and your studio, dude, you're rocking! When can I do a workshop there?
As I looked at your images a couple of things stood out, one, styling. You pay attention to detail real well with the "shiny" on the rocks. Model's styling is hot too. But, you obviously have a fog machine and to me the fog is coming from the monitor's right--next time use dry ice so the "fog" stays closer to the bottom and goes up more evenly.
With fog machines it's like someone took a water house and sprayed it across the back of the image when you place the machine near the edge of the frame. It's almost like a pair of black lips on the tiki torch pole there on the right. Notice how the fog is moving on the left and almost still on the right, like the button was held then released on the machine--the burst effect of fog machines? In the one you chose it's going from right to left (on the monitor view) and obvious. The fog is barely there in #1, but there and looks like fog hugging the ground, similar to dry-ice and more realistic.
Just my thoughts and it's great to have someone with your background here, now I'm not the only one using Cinefoil. Thanks for sharing and thanks for being a part of this community and family, and I'm serious about heading that way! Thanks again, rg sends!
