Good Mood, Poor Emphasis
I'm at a mixed feel of this track, I'll try and break it down into positives and negatives.
Positives would be the potential I see for this song, I absolutely love that you were able to morph this song into something more than a hard sounding song, and actually turned it into something eerie, in a sense, the final battle is SUPPOSED to feel eerie, I mean come on, that fight is both a long haul, and it's creepy! The aura of the song also seemed to give me a feel of what the background should have been. If I recall correctly, the background in that fight was almost non-apparent, this eerie song tends to give it the background it needed.
Now for the negatives, part of changing the song a bit with the eerie feeling hurt how the song felt, some of the effects seemed to "carry over" when the next part of the song was transitioning. As well, I felt that some of the main parts of the beat were not apparent in the song, which weakened its impact a little. If you want the song to be eerie and scary, perhaps emphasis on those a little more, and give your listeners a bit more of a scare.
I think the track overall is one worth listening to, that's for sure, I just think that it could use some tuning up. As a big fan of BoFIII, I thank you for giving your great effort to this song, and all the BoFIII Songs you've worked on. I hope to hear more from you!
