I like it, it adds texture more than anything. I wouldn't even consider it "lead guitar" until the very end, possibly, but rather its more like some rhythm parts. I dig it. I would probably have it lower in the mix until the lead part in the end though. I like the main riff in the song and wouldn't want to drown that out. But I think your lead part at the end works really well. Is that an acoustic you're playing throughout?
I may play with the mix a bit, but the parts really work. I have a feeling that this may be a dense one when we're done with it. I envision adding vocals and synth.
Good work rezzeJ, thanks for adding to it!
