Really awesome video! One of the best I've seen as far as cardistry goes!
I can't believe you actually leaned forward on top of that building. I thought you possibly just turned around (instead of facing out, faced in) and leaned forward towards the parking lot because you couldn't tell from the shot angle, just like magicman384 said.
Anyway, very gutsy to lean forward! If your girlfriend was filming I'm sure she freaked out with you leaning like that! lol
