I really dig the main guitar part. I think the acoustic does it a lot of justice, but I do agree with firesole about the solo, I really didn't feel it. I think you could have done more with it. I would definitely take Firesoles suggestions into consideration, but if it feels right to you, then thats way you should go, it should be definitely be your signature. Take Scar Tissue by the chilli peppers. Totally lackluster solo, but it's "right", you know what I mean? Overall, I like the song man, I can't tell you how much I dig the acoustic sound that you got! I would just record the parts over again with some better equipment and play around with the mix until you've got a gem.
