Band on a budget - the recording process part 18

Righty ho, well, our guitarist came over a couple of weeks ago and we completely re-did the guitar part(s) for Words.
Took about two hours to get the sound we were after, the core part done, and then the more complex bit of recording the solo whilst he came up with the parts - but that doesn't seem unreasonable.
I must fess up at this point and say I made a mistake with one of the recorded parts whereby I duplicated the two channels I'd set up but didn't notice that in doing so Reaper doesn't automatically set the inputs the same as the duplicated channels. So instead of my two new channels recording mics 1 and 2, I had two copies of mic 1. Because both channels were recording fine, and the bit we were recording was tonally different to the stuff we'd already tracked, I didn't notice until later.
Fortunately the mic that was recorded was the main one for that particular part.
Anyway, I mixed it all up and came up with this: https://soundcloud.com/the-southern-wild/words-20171105/s-Kh5N7
That I was reasonably happy with until I posted it to be reviewed on the Sound on Sound forum.
I am no longer happy with it.

Feedback I need to work on:
There's a harshness around 2kHz, especially at the end section.
The electric guitar is a bit too loud (I'd thought this myself on a re-listen).
The acoustic is too thin, lacks lower mids (I had thought about this as well but was willing to trade it off against things going too muddy).
The distortion on the vocals at the end is too much.
Needs a bit more reverb to make the whole thing sit together.
With the exception of the bass and vox, everything is too compressed. It's a mush.
The guitar solo disappears too much in mono. Might be worth separating that out of the rest of the guitar work and bringing it a bit more central.
Vocal levels need to vary more, to breath with the song a bit.
Low mids are bit empty (see comment about avoiding mud above).
Vocals are a bit dry.
Vocals are a bit thin and, linked to that, a bit too loud. Could probably do with a bit more de-essing as well.
Are the backing vocals in or out? Need a decision on that.

The frustrating thing is that, with the exception of the reverb and vocal thinness comments, I think that deep down i knew most of that anyway. I'd just convinced myself that was good enough - or at least, as good as I could get it.

So now the question is whether to try and rescue it from there or start again.
Decisions, decisions...
