Light was too directional and too hot on the forehead.
Seems like he needs a big(ger) softbox, close(r) to the model, at maybe a lower output (to let the background fall to black), and maybe a bounce card on the left for fill.
Actually, I think it just needed to be lower with maybe a bounce under the model in front.
The pose itself cute, but has no catchlight in the left (model right) eye which throws the balance off. And the pose isn't suitable for an actual headshot, as agencies (almost) always want a dead ahead look.
