the only problem i have with this is it's way too repetitive. you could possibly break up the repetition with a break or something. it's just missing a transition or two. the intro could use something to help push you into the song. like a slight increase in volume or something. around 1:32 you kinda do a build up but there isn't any noticeable change. and the ending really drove me crazy with the clashing notes. it may have been done on purpose to give it some kinda of character, but it just doesn't sound "right". this has potential to be really really catchy, you just gotta break it up into sections and have changes in repetition and dynamics. that's just my opinion. take it with a grain of salt.
