Impressive.
Its good rearrangement and it takes talent to do that seeing you didnt just go "lol copypaste over another track" The song in my opinion is a bit higher than the original one in pitch, atleast piano seems like that which I dont mind. You also added quite some nice things over your own like a choir, female choir which I dont remember in the original one which really nailed the whole vibe. I will how ever be an evil troll and give it a nine because I preferr "emotional" songs being more in the style of I am legend track or Frank's Death - Soldiers (Requiem In D Minor), Still,it is a good piece and alot of work and effort has been put into it. The quality is crisp, clear and the instruments fall together in harmony. Keep it up Peter
