Overall, I like the concept here. Your execution needs a little work. In particular, I don't think you've got good focus on your subject. The sky behind him is a bit busy, and I think a tighter crop would have made your composition much stronger.
This shot has a real classic feeling to it. Like looking back through your mom's photo album. Technically, the clouds are WAY burned out on the right but I don't care, I like the FEELING this shot creates with the viewer. Well done.
