You have 2 major problems:
1. the acousticc guitar has too much lower mid frequencies. Try using a high pass filter and cutting somewhere around 125 - 150 Hz (you need to keep the acoustic from conflicting with the Bass).
2. You have some kind of compressor/limiter that is pumping like crazy. Slow down the attack , and try less overall reduction. Everytime you hit a down beat you can hear the comressor ducking the level.
I would suggest you take your raw tracks and go ask someone at a recording studio to mix them for you. You vocals sound great, the songs are good too, don't waist that because you can't scare up some scratch to get things mixed well.
