Yeah but what about her pose is really provocative? She's sitting in the sand holding an umbrella smiling. She's not laying on a bed, she's not exposing really sexual parts like cleavage, she doesn't have her legs spread or is bent over, she doesn't even have a provocative look on her face, just a smile. If all these things really scream porn to you then I give up trying to talk you outta the idea.
Gorgeous choice of color with the greens. It gives this shot a cooler color tone than what you usually see with beach pin up shoots. The dark clumps in the sand also add a delightful touch of texture and detail to the shot.
Haha I live in a smaller town so the 'beach' is never crazy packed and I think we were just lucky, there was a bunch of people around but mostly they stayed out of our way or I had to wait for people to walk in and outta the shot every so often
