there is potential, i can feel it, now this mix is a bit muddy, ignoring that it's a little outta key, (learn scales, they'll make the most beautiful melodies ^_^) i would use the slope tool on low note instruments, and use the highpass option, Highpass is a method mixers use to completely mute lower frequencies, if you have too many lower frequencies it can make the mix a bit muddy and make it very difficult to hear everything
