(The cello needs some space of its own (in a bridge, f.e.). Now it looks it is competing with the sologuitar (and loses...).
Its a bit a pitty I can only hear that instrument more in the beginning and the end. Maybe you make both instruments play more together (like 'answer-question'). Lets say I thought that on 33% of your lyrics, you should let a computer generate something random instead? Amounts to the same thing. I'm only in it for the fun, if you don't do fun that's okay with me!
