Well, hello there, Heat! Only yesterday I was wondering to myself what happened to you.
I really like the pace of the song, the melody and the singing. The drums seem a little low and dry, but I assume that's your style. When the rest of the instruments come in I think it sounds a bit crunchy and harsh - is that a synth that's coming in at about 11 o'clock? As triple M said, it's a bit crowded, there.
Good song, probably mixed exactly as you want it.
[edit] Realised I was listening on my tracking phones, not my listening ones! I really like the intro guitars, very warm and intimate. The bugbear I have is when the song kicks into the second part there's a disagreeable (to me) crunchy distorted sound mixed in with the organ. I'm probably way off here, but it sounds like a bass through a really lo-fi fuzz pedal or something. It might work better if the two sounds were separated by panning. Nice lead part later on.
