You did a great job capturing this model in a perfect pose and gaze. Your shallow depth of field makes him pop off the background in a pleasing manner and the bokeh is beautiful. His dark clothing further sets him apart as it contrasts with the greenery and warm sun behind him.

I do believe this portrait could be even better with a few adjustments. With the model facing to the left, a bit of lead room (i.e., leaving more space in front of the model on the left and less behind the model on the right) would make the photograph more attractive. Additionally, the placement of the sun right above his head pulls my eye away from the face and eyes causing a minor distraction from the area with the most impact. Both of these adjustments could be obtained by moving yourself a few steps to the left and recomposing the shot.

Overall the portrait is appealing and the models expression leaves a great impact. Good work!
