OK - first of all, it's pretty good!
But, here's what I would do...
I'd LPF the acoustic guitar a bit higher than you are - assuming you are - kill of some of the really low frequencies. Might be a matter of steepening the curve rather than changing the frequency - not sure what you've done there, but just a bit less bass - not much, might make it better.
Then I'd hunt down the fundamental frequency for the second chord and put a bit of a notch in it via EQ - it booms a little more than the others.
Then I'd put a bit more bass back into the lead vocal to compensate - seems a bit light on. Might also try something on the top end of the vocal - there's a bit of harshness there that, so with a notch filter you might reduce it. Put another notch filter on your EQ, max the gain, and sweep up and down looking for it. When you wince, you'll have found it. Take it down a few dB and see if that isn't more pleasing.
And I'd just do some manual adjustment of the lead vocal volume at the start - it starts a little quiet. And when the vocal is happening, possibly pull 2 dB off the electric noodle guitar. Tell Rob I'm sorry...
But all in all, not too bad at all TwoDogs - and these are just minor tweak recommendations. Others may disagree...
I also agree with ray that an actual bass line might make it all hold together a little better - depends upon what you're trying to achieve though.
Cheers
