Well - not a bad song, and pretty decent playing and singing, BUT- It's drums, and a few other things lurking in the background. Did the drummer mix it? The drums were very up front - and convention is that the singers tend to occupy that position, with drums behind them. The drums also have the sound you typically get on Jazz - a more distant 'single mic' kind of sound. The bass is a bit murky and practically everything needs EQing - but we don't know how you recorded it? Live, or overdubbed? It's not bad (bar the weird beginning noises) but maybe you were stuck with tracks, or mics, or monitors? There weren't any instrumentals, were there?
