Seems like you put the wrong link; it's

Lovely song, though country's not my thing. Mixing could be improved, indeed - you said on the description of "Big Sister Now" that mixing wasn't your forte, after all. I'd rise the volume of the drums (or just compress it, perhaps?), cut the lows (200 hz and below - a high pass filter should do the job) on the dead notes at 3:43 and have some treble in the whole mix, perhaps compressing it a bit.
No complaints in regard to composition; the chorus is catchy as hell and the transitions are smooth. c:
