All in all, really impressive effort. I saw a few Amy's at a party last night and they were lame. The real Amy is prob impossible to match unless you went to perfectionist extremes by say sleeping under a truck for a week, growing out your underarm hair, and taking a few trips down some staircases face first not to mention all the chemical refreshments.
On a sidenote and at the risk of sounding like some ADT fanboy asshole, you don't seem to age.
