On this one I find that there is not so large a tonal variation as you normally put into your images. I wonder if it would strengthen the image if the man's shirt was lightened in tone?
I also think that the graphics on the wall behind is head are a little distracting?
That looks better to me, Antonio.
I suppose you could clone out parts of the background but it would be quite a lot of work for little in the way of improvement. So I would leave this image as it is now.
