Interesting, Keep Talking...

first of all,actually when i critic some any image,i look at 3 components in the image, meaning,the object,the colors with the light.
the model's body is without doubt sexy especially the bottom part,the pose reflects a great passion,by putting in consideration the sharp look of the model we will figure out a wonderful mixture of beautiful hidden meanings of Beauty,I think the shot would work better if the symmetry were slightly nearer, with a bit more space to the left of the model - not a difficult edit.this point is not peculiar to this image but to many of your gallery, when you shoot the model again, I'd consider shooting from a few inches LOWER, which would favor her upper body a little and gives a wonderful sight to the lower body,another important thing is to the bikinis she dresses ,some new sexy ones are needed here too.by going back to image, the simple background and sun lighting works well, but There may be detail still there that you can edit more perfectly.I hope my criticism was fair enough and pardon me if I was tough a little bit, because i tell my opinion honestly. ^^
