Now then, i have a feeling this is going to be a somewhat long review. Heh. Prepare yourself.
I personally believe you fulfilled the mission you tried to complete when you decided to make this, although their are a few things i believe could be done better. First and foremost it is a brilliant and powerful piece.
Firstly, the aura generated at the beginning through to around 1:05 actually had me scared. The darkness created by the song was ever present and it felt like their was no moment for respite. The claps of thunder did especially well to help make the listener feel small, overpowered.
The dark voices as well did great. However, the 2nd voice at 0:33 ruined the dark feeling for me as I could hear the voices strong american accent (sorry if it wasn't american). Thats one thing i would fix. But the other voices sounded much darker, more sinister and were perfect.
Secondly, the texture change at 1:06 was perfect. The gunshot shocking the listener, with the song transforming from a more sinister and scary one into one that overpowered the mind with the feeling of sadness instead. The soft stings making the heart throb along with the sound of the rain. And the occurring claps of thunder reminding you that the world of darkness, and evil is still present. Even during the time of mourning and loss.
Thirdly, at around 4:14 when you begin to hear the birds come in. I loved this, just the addition of the sounds of the birds at this point served as a slight texture change, helping to progress the mood from sad into hopefulness as the song ended peacefully. A reminder that at the end of each day, at the end of each bad time ,there is room to great another great.
All in all, a powerful, moving song. Very powerful with only one minor problem in my mind, not enough to mark it down through in my books. You did a fantastic job. I'm definitely going to write a story to this. Right now, Haha.
Keep up the truly amazing work,
I'd love to hear more from you.
