Very nice production..
Dont like the synth that kicks in at 1:58 and i agree with daze the synth at 3:53 is not my cup of tea, and at 4:35 its all goin out of control... ..
the pad at 6:16 sounds like forced upon the track..
i think u just need to work on the melodies, and the synths could be more psychedelic..
all in all good production, keep it coming... !!!
