Hey man...I actually like this a lot. The acoustic seems to be recorded very well, in my opinion. I spend more time on acoustic guitars than any other element of the mix, and there really aren't any bright line rules as far as I'm concerned.
For example, people tend to put way too much importance on the room that you're recording in - some are just plain silly (in my amateur opinion). I'm not saying the room doesn't matter, but honestly, as closely as most people mic acoustics, the reflections you may be getting shouldn't make you pull your hair out or anything.
Some people have hard and fast rules about where the mic'ing should take place, but guitars aren't fungible instruments...no two are alike, even the same models from the same manufacturers. One inch can make a HUGE difference, though...you just have to really listen in the cans and in different takes in different positions until you get the sound you're going for.
Sounds to me like you're going for a more natural sound, which is totally cool in a solo piece...it may or may not work in a mix. Just from listening to that clip a couple of times, I can tell that you'd probably have a couple of EQ hot spots you'd want to focus on if it's going to be sitting in a mix with a bass and/or other guitars. I can almost guarantee you that there's nothing on an
acoustic guitar track below 100Hz that's worth keeping in a full mix. And on that particular guitar recording, I'd probably notch it downwards a bit fairly wide centered at about 315Hz for starters...it'll rob the track of some of the body, but there's usually plenty of low mids in everybody's mixes without clouding it up with acoustic woofiness.
Again, I actually like the recording as is. I think you have the fundamentals down pat, personally. If it was going to stay as a solo track, I'd actually probably mic it very close to the sound hole and then roll off a lot of the low mids...really close mic'ing of an acoustic can give it a presence that's just not possible to obtain through EQ or compression or any combination thereof.
So there's my longwinded way of saying...nice job, good luck, and keep recording, LOL.
