Let me start by saying wow!
Amazing introduction! The synth lead timbre was just about right, as well as the effects. Though, the effects volume was slightly too loud in places, it was a little overpowering - I wanted to definitely hear some of that melody!
When the drums kicked in, nice percussion - though the drums were slightly too loud and overpowering the whole track I feel. I couldn't listen past 4:00 as my evening tastes are more downbeat, ambient - but what I listened really sounded great!
Now of course I'm not a huge production guy - I'm just more into the music side of things - but I think it was spot on here - just touch up on getting your levels right - as I said, the effects at the beginning in places was too loud!
Keep it up! Nice one!
