I'm very happy that you also did not just snap a picture of the rock but actually did something creative. The model has a great expression for the occasion and lighting is good. Composition is good also.
Clothing, hat and gloves are all appropriate for the setting.
The combination of the gold and his look makes the composition very attractive.The sparkling gold and his hands are superb with your perfect POV.
Congrats,

I like the image and composition. The first thing that strikes me is the glare off the "rock"...it distracts. Also, I think it would have been better if his eyes were toward the rock rather than toward the lens....too much white in the eyes.
Love the eyes, emotion. Light is awfully harsh on the gold, but I like that. It competes with the eyes and completes the context and story. You did a fantastic job of maintaining a consistent tone though out the image. Very impressive.
