Slow build - Decent Track
While the build is slow, it picks up in a nice way. I thought the track was going to "get going", so to speak, but then it chilled out again, which was a bit confusing. I liked the string work near the one minute mark. It sounded pretty good. No complaints there.
I begin a new paragraph because you started a totally new song. It came from out of nowhere, with no warning. I wasn't a fan of that transition. The new song sounds alright. I would suggest thinning it out a little, as it sounds clustered to me. Somewhere around 3:20, it gets much better though.
After that, there's a pretty nice transition back to the softer sound. I liked that a lot more. And after that section, there was a swell used to transition back to the more upbeat part, which was good.
The song also ended well, with a fade out of a small organ(?) riff.
Overall, I'd say it's a pretty good song. You should work on transitions and mixing though. Some of the upbeat sections sounded a little cluttered.
