Yes, he does look very worried. I wonder if this is a candid moment caught or posed? Very well done overall but the light seems a bit harsh, the shadow on his nose is a bit distracting and his lips look off for some reason, the color doesn't look quite right, almost too pink. The crop is well done though I would have liked to seen the whole chin to balance it out a bit more. A 5
This is not what I usually think of when I see the word portrait. His expression is rather disheartening and makes me wonder what stress is going on in his world. Your lighting looks to be a tad bit harsh. If some of your light came more from the side, this would soften it up a touch and help even out the skin tones.

Great focus and detail. Filling the frame is important in portraits, and you've certainly done that. The worried expression creates an emotive response in the viewer. :o)
This doesnt really portray a studio shot in my opinion. The crop is extremely tight. I would have zoomed out a bit, to include at the least, the rest of his head and probably his shoulders.
