On my good play back system it sounds full spectrum... lots of bass.
If I were mixing I might try for a bit fatter tone on the kick, but I'd clear out some room for it by trying to get more attack on the bass notes and then cutting some of the low few energy witha very soft lo-cut. That would make the kick more apparent without really turning it up. The bass almost sounds muddy... but I'm not saying change your mix... some people like that exact tone. I'm just saying how I'd treat the song.
I'd also ride the organ a bit towards louder, but I'd back off it's high frequency a bit so it doesn't compete with the guitar as much... I'd try to really use it as a pad and glue. There are places where the bass is on top of the organ and I'd try to gel them up into one vibe. Not every where. The places where you lose the organ seems spot on... it lets the bass figure pop out.
I really like the edgy guitar tones. They have a sort of aggressive mid freq character... that reminds me of what I hear in real life... I like that. I think I'd give them a little extra lo-cut as has been suggested and see if I could get them to sound a bit airier without adding any more aggressive bite.
Then I'd fold it all up in some light reverb. It sounds like a band playing in a room. I'd use reverb to reinforce that impression.
That's how I would try but I also think what you have done seems confident, strong, and fully realized so there's hardly a need.
all the best,
