[LAU] a strange little song..

Hi everyone, I just recorded this song last night on qtractor.. guitar thru vamp2 bass direct in, vocals thu Sampson C01 and Behringer minimic800. Drums.. soundfont.. and spent 2 mins on them !!:) http://drop.io/jjoskmy I think the song is way too high for my vocal range, and the mix seems very suspect, but I'm not too sure about how to resolve it.. This is actually a song I wrote for my band (with a female singer), which never seems to work very well, and I wanted to record it myself to see where we are going wrong - I think I recorded it way too fast which isn't a good start - should be more like 100bpm.. beyond that, it also needs to be really tight to sound even slightly OK. I'm really considering dropping it - but suggestions about how to improve the overall sound/composition would also be appreciated! James
