I love those guitars and strings! I think you've done a great job with them. Only a couple of things caught my attention for improvement:
You should automate the lead vocal a little bit. For instance, at 2.57 that 'now' sounds low, and the same thing happens at 3.12.
The percussion should have more body. I think it sounds a little bit thin. I mixed that song a while ago and I don't quite remember how I did it, but if I had to mix it now, I would probably try to give the percussion very similar EQ to the one I give to toms in other songs.
