LOL! Hilarious concept and a lot of really funny shots and ideas within the piece. There were (only) a couple shots where I noticed lighting, the one I can remember was that the cafe was dark, maybe a shot of the side of him(you) would have been better so the windows wouldn't be behind the subject.
You did a great job on the make-up but one tip when doing old-age stuff, the hands are the biggest giveaway of someone's real age(they don't really have plastic surgery for hands, it would seem), so don't forget to have some wrinkles and liver spots on those babies, too.
But yeah, I loved it, I hope it does well for you at the fest/comp!
