I really enjoyed the intro into the first main segment at :50 or so, after that though the track loses my interest just a little bit -- I feel as if the transitional portions between the fuller parts kinda outstay themselves just a bit, even though the full parts are definitely worth it. That being said, the synths and pads you're using are all very fun and bouncy!! 3:02-3:10 is awesome!!!!!
Congrats on yr friend's engagement!!!!! very nice of you to make a song for them :)
