I think you talked about doing this a month ago haha. Well I'm glad you're making some process on the song. It seems like you keep coming back to this one again and again. Anyway, so far, I'm digging the demo. Honestly everything seems to fit. The instruments work well together and overall it flows quite nicely. I'm not a fan of mellow techno all that much and If you had told me this is what it would have sounded like I might have written the melodies a bit differently. Overall though, I enjoy it.
By the way, at parts it sounds like the song is about to explode into something truly epic but I was let down a bit there. I can't put my finger on it but thats all I can say for now. Great job so far, keep it up.
8/10 for being a god damn demo =P
