Well that story sure does feel familiar to me! =p
I like the way it's shot, quite nice camera work. The audio though needs some improving, particularly the early outdoor scene. Try making the music play throughout the whole film but with altering audio levels I'd suggest. It feels more like a few scenes strung together rather than a cohesive whole.
Hong Kong's an awesome city though and you're lucky you got to shoot there! Wish I'd been that productive when I was younger and went there...
