#1 feels a little empty, #2 sounds really cool. #3 has sort of an old school flavor to it, pretty nice. couldn't really get into #4 for some reason. that synth line is just not all that great sounding.
on page 2, #5 sounds pretty good. i'd turn up that piano-ish sounding thing thats in the background, and where's the snare??? with some hats and a snare this one could be pretty nice. #6 reminds me of the 90's style from the bay. simple yet effective, very nice. #7 is kinda lame, sounds like some weird video game music. #8 has a definite 80's feel to it, which could work witht he right person doing vocals over it. very retro, i like it.
all of your beats seem to have a certain atmosphere about them, which is easy to get into. they all feel "related" or something. you definitely have your own style going on, good work dude.
