The hair seems to be a bit much. Long and grey is good. but to much on top. A couple years ago I found a wig top that was a balding, so had hair only around the sides. Besides that looks like a good start
You look pretty good already, but I agree about the balding wig and the grayer skin tone. I think your eyes betray your youth, so I would consider some colored eyedrops - that would be the coup de grace. Hope this helps.
