Great cleanup up on a really badly damaged photo. Yes, he does have a mustache. There are two things that stand out and that is the color correction. If I do a color correction of the original my colors are different from yours. His skin is paler like you would expect of an older person, His suit I show as being blue and not green.
We used to shoot volunteers who added a vignette to their photos, now we simply charge a $500 fine. OK, seriously I know your background was trashed and you were trying to give it some depth. To do vignette right, you do not want to have it jump out at you and be able to see a clear image of where it is starts. It should fade out so seamlessly as to not be noticed. You don't want to have it look like a spotlight on him.
