Real late on my reply, but meh.
I think the song's great. It's very powerful. Full of emotion.
Nah. They really insulted your work. What can you do? So what if the ending wasn't uber climatic? It doesn't hurt the song too much. If you just listen to it without devoting 100% of your attention to it, you don't even notice. I think the ending's fine, personally. It's smooth. Now, if you took it and had drawn it out for 30 seconds more, maybe I'd agree, but you didn't, so very nice work.
At first I didn't like the transitions very much, but they really grew on me. Now it's a whole new story. I think it was because I was so into the impacting smooth sound before 2:50 (I think around there). Though now I don't really mind them.
Like I've said before, the song is very powerful. You must have some pretty good equipment in order to generate something that sounds like it could be in an actual PS2 game like this.
Look forward to hearing more.
