It's very smooth and mellow right up till 1:03 where, personally, I find there's a bit too much going on with the new synth especially around 1:17 onward...but I had a listen at the second concept and this one's first minute blended with concept 2 could be really unique.

Oh damn, what a beautiful and relaxing song. Great cool melody in this one dude. Perfect synths.
The low frequency would need some more presence and I think the looping could've been much better. Or will you work this out to a full song?
Still, this is an awesome tune. (: Keep up
