Ok, I got the file. You have to be a member and logged on to the site to get mp3.
I agree with most of everyone elses comments, the guitar should come up a bit. The whole track could be louder, but that's no big deal, to me anyway - move a fader. The background noise is pretty evident, it's unfixable without retracking so it's a non issue. I sorta like the ambience it creates. You record outside or what?
Very competent guitar playing, nice sound as well. Nylon rocks. I like the singing. Some of the vocalizations at 1:03 bug me a bit - At that point I'd be tempted to add some variation in the mix. via another guitar comming in from another pan perspective, and a change in volume/effect on the vocals. But that's irrelevant, if your idea is to keep it guitar and vocals, I think you captured it well enough. The song comes across, and that's important. I can hear the Beatles influence in there especially Paul which is a good thing(you know that).
Good stuff, look forward to hearing more.
