Okay, I've taken a completely different approach ... maybe a bit radical
It's a good character image but the background is very 'busy' and as Willie says above, doesn't really show a baker's environment, except the Hovis poster on the left hand side and I had to look twice to realise that's what it was. (Personally, I like the tongue - I think it adds a sense of humour to what could otherwise be a very worried looking baker!) Also, the colours in your shot seem quite saturated (might be my screen, although it is calibrated). As you don't say what aperture you used, it's hard to guess, but the background is neither in focus, or sufficiently out of focus not be distracting.
Soooooo ... I thought that with a face as full as character as that, I'd turn Mr Wilson B&W (see my mod). I also did a quite tight, roughly square crop, and took out the background completely. I added a very slight S curve to give Mr W a more gritty feel and boost contract a bit. It seems sufficiently sharp to my eyes, so I didn't do anything there. And yes, I did crop the ear on the left deliberately ... don't know why, just looked better for some reason than the whole ear *shrugs*
