You need an EQ dip at 250Hz about -3db and a possilble high pass rolled off below 100-150 Hz. The guitar is very boomy and it covers your excellent vocal.
Regarding arrangement, you have verse, chorus, verse, chorus, pause, repeat tag line, many times.
You need a bridge after that 2nd chorus if your going down the path of v, c, v, c. The format screams for it. Then either a short solo at the end of the bridge or another v, c and then do your tag lines.
Instruments I hear are drums, a really funky gretsch guitar with some wah action. Yeah, I heard the Beatle sounding Eleanor Rigby strings back there somewhere.
