I echo the compliments to you on the lighting and composition of this work. The fact that the model has not done previous bondage modelling makes the photo more erotic in my eyes. First time in ropes (other than what might have caused those other rope indentations on his back).
The use of the cloth for a blind fold is a nice touch, too. It adds softness to the photo, and maybe a little tenderness towards the man. The tilt of the head looks as though he's listening for something or someone. Nice pose. I wish the cloth didn't extend quite that far down so that the rigging could be seen better, but that's minor and a personal preference.
Thank you very much for your feedback. This was indeed the model's first rope session. The other rope marks visible were from the first harness we tied but the pictures didn't quite kick as much as these ones.
