I thin k the camera is far too close to him, and his beard appears to be unusually large, and the top of his head unnaturally small, due to too close a camera placement. I agree with Tirdiron,. the key light is too far off to the left, and the right side eye is bordering on, yet not quite "dead" (there is a teensie bit of iris definition, but no catchlight).
THe back light ratio is too high, and his mouth area is an unappealing, black void. You can see his beard being blown out and lost in the excess blowback from the background on the camera-right side, but overall, the brilliant, over-lit white backdrop is also not working well with the somber, "heavy" lighting pattern on his frontal areas.
Knowing that you shot this with Speedo Brown Line, I would suggest that in many cases, there is a real, genuine need to add a third light, to get you into the 3-light power options, with 140-140-70 at full-power on a D402 pack in Asymmetrical output option, even if you just aim the third head into the ground, you WANT a lot less power sometimes on the background. The white is over-lit for such a dark,heavy-shadowed front.
