photolady95 beat me to it, I agree a light crop will do it. By taking off a bit from the right you also cut a bit off the wheel but I think it makes this more appealing even rather than not.
When I experimented with the image I also straightened up the falling lines or though I think they also work. Matter of taste I guess. But a little more foreground crop and a smidgen from the top I think would also benefit. But all this is entirely a matter of taste. You finish up with a pretty tight picture now but it directs the attention to the mean persona, right ?
A bit more Clarity perhaps ?
Cheers
P.S. I hope it is not his bike, that would ruin his image !
