I like the vocals i think you could get them a bit more stereo, chuck on some chorus/reverb/duplicate track/ Widen top end a bit more, don't know if there's enough hats in there but its sounding good. The bass sounds a bit flat to me and the snare doesn't sound too good to me (needs more punch) Piano sounds good but goes for too long without enough variation. Definitely would like to hear finished version. Also if you don't mind sharing I'd love to have a go with the midi (don't worry i have good intentions i swear)
