This is an NGADM 2015 review.
So, I have to give you props for having this song almost entirely recorded. I think there were only one or two people that did this in all entries for round 1, so nice stuff! This song is pretty enjoyable for its psychedelic nature and it's a pretty interesting piece. Most of what let you down was related to structure and production.
Most of the issue with the structure can be written off as stylistic decision, so I won't drone on too much about that. It's more that some parts catch me off guard a little, like that bass guitar at 1:50. I find it a little chaotic, especially with the crashes in the background being quite constant. Anyway, other than that and probably a few other small moments, it was generally quite sound.
When it comes to production, you've got one major issue - your song is really quiet. I can't download it and put it in my spectrum analyzer so I don't know exactly *how* quiet it is, but it sounds like it's about -18RMS to -22RMS. I suppose this isn't a massive issue, and it does mean you have a lot of dynamic range to work with resulting in a nice spacious mix, but you really could bring it up a lot with literally no detriment to the sound. Anyway, the other problem is that your balance is pretty off - the percussion is extremely quiet at points, especially compared to the bongos, which are inexplicably much louder than the actual drums most of the time. I'd suggest comparing your pre-mix to a reference track that sounds like the mix you eventually want to end up with, so you can use it to help you find what levels are appropriate for each instrument. Again, a possibly unorthodox intentional decision, but I need to be fairly objective to write a helpful response :P
Anyway, apart from some production issues this song was generally enjoyable and a pretty nice listen!
