It's probably too late now, but I'll just add some observations:
1 The kit sounds real nice
2 I'd prefer the bass guitar to have more bottom end.
3 I'm not sure what I think about the jangly guitars. At the start, when there is just the single one, it sounds, well, jangly and a bit abrasive. When the other one comes in and you get the big stereo spread, it makes sense. The after a while, it starts to become intrusive . . . so maybe there is a point in the song where they need to stop and give the ears a rest.
4 The lead, given its role, would benefit, in my view, from having a bit more presence. I like the sound, but it seems a bit squashed. As it is, it would be perfect if it was doing fills while vocals or something else ran over the top.
The musical elements are all there, but I can imagine it sounding a bit more dynamic with some playing with the mix, and maybe the arrangement within the mix..
