I am torn between two of these photos:
"Metallic Pasties" and "Bedrock"
Photo #1 plays with a second shape on the model's body, both hiding and accenting it partly. the golden glow on her very tan skin looks beautiful. On total, the photo has a very warm tone, and the blue sky offers a nice, not too harsh contrast.
Photo #2 uses a similar effect, but instead of golden, reflecting flakes, here almost white stones get used, which make a bigger contrast. Also, as the background is of the very same stones, it's like the model is both partly hidden by stones, and stands out very much against the stonesin the background. Smooth on rocks. The colours are much calmer and cooler in general.
If photo #1 was more HD, the decision would be way easier, but even as it is, the golden glow and the complete mood makes me choose "Metallic Pasties"
