3 light setup?
I think your Fill light is too much for a good lighting ratio. It's obvious you have a (Key ? ) light camera right, but your Fill is not allowing any modeling from the Key. The chin shadows are creating an even shadow beard. The lighting ratio on his shoulders/chest is good, but portraits are about the face.
You have good separation from the background, but why are you lighting his back so low? The separation should be concentrated more on the head and shoulders. Notice the highlights in the open area at the lower left in frame. The "hole" between his right arm and torso has a halo. Raising your back light vertically or flagging your source would eliminate this.
I bet his hands are in his pockets. Next time try having him move one leg forward and place the forward foot in line with his rearward foot. Then have him place his weight on his rear heel. This will shift his hips, thus his torso, thus his shoulders. Thus creating a more dynamic pose rather than the football shoulders we see here.
Overall...... better than most are posting.
Just my 2¢. Thanks for sharing.
