This comes from someone who doesn´t know to much about piano. The recreation is more or less accuarate, the second half is were there seens to be some problems, mainly that either some notes happen 1 second before or after they should.
The slow tempo gives off a different feeling compared to the original music shown for that infiltration video. You arrangement sets off a tragic feeling, almost something sinister lurks nearby and searches for its prey....... That's the vibe I'm getting from. If you ask me how that is, I say you've accidentally created an interesting take on the original piece.
I appreciate your comment, Wazi. The different atmosphere is no accident, by the way; I wasn't aiming to replicate the sense of urgency that the original piece has. On the other hand, the arrangement has ended up sounding more somber than I would have liked. lol
