I don't think you want anything louder. The loudness is just fine. What you need is more clarity. For one I would dial down if not remove the saturation on the instruments. You have a lot of high end sounds all clashing, I might try EQ-ing off some of the high end on some of the parts such as the bass. Scooping out some frequencies on instruments to make room for others. It's hard to say more without being able to see the track.
