obviously i will always prefer the original, since it's Jesper Kyd, but also because of Nostalgia, and generally because it has a different tone.
There's a lot of things you achieve here that is amazing, but a few things are wrong, for example the beat is too "noticeable", as in, it almost feels like a dance track.
The end part, while different to the original, sounds very nice and appropriate too, might be a bit too long though (the piano), and that you end it abruptly

GREAT WORK :D

I can only agree with you, the music of the Hitman-series is awesome and the game too :) you make a very cool track. It would be fine if you mix from the other Hitman-parts the musik, that would be cool ^^
