a good try

it was alright but it felt empty, you only had one or two layers going in any one section, unless the minimal approach was your intent but using a word like symphony in the name implies a bit more depth. plus the song had little flow, it started off like it was a build to a breakdown then just turned into one section tacked on to the next with little to do with each other. not necessarily a bad thing, but it's somehing that bugged me personally.

interesting sounds you used though, try tweaking your lfo's a bit more to get some variety into them
