Big welcome, Tiziano, nice name :)
Good subject and nicely placed in the frame. I think it's a bit high in contrast, maybe you could use an inverse curve to tame the whites. Tutorials on hot-to in the Educational Resources Forum)
If this is something you do, I may remove the bill shine.
Will be looking forward to more from you!
Welcome to BPN, Tiziano! Very nice first post. I like the sharpness, eye contact and setting. Adding to Fabs' comment, I would try to get more details in the blacks. Keep them coming!
