i love vocals like this!
alright few things to say already just by the first 10 seconds
the 8bit styled sounds are just holy fug i love them!
that 303 synth is very nice
ehh the vocals at 0:18-0:20 need a bit more well tone to them as it kinda sounds like your singing into a mic for the first time and your embarrassed by it but your not singing with rhythm (dont mean to sound like an ass :P) you should try doing some octave layering and well thats about it actually
i must say though you have a thing with vocal mixing as the vocals fit perfectly in this, quite amazing actually especially if this is your first time putting vocals into a song like this
i cant wait to hear the finished version though, keep it up! ^_^
