I like it, has some nice ambience to it. Might want to consider sliding the volume of the starting pluck instrument down around the 10-20sec mark to let the background instruments more into the front though.
Keep up the good work. :)
Heh, don't underestimate the impact subtle details can have, many iconic NES era tunes had only 5 channels to work with and they milked em for all they were worth. ;)
