I feel like at 58 seconds, it should drop a bit harder. It also sounds like some reverb carries into it, which you could just mute the channels that aren't being used in the next portion to clear up a little space in the mix. The overall mixdown needs a bit of work, which isn't a big deal though, cause this is still a W.I.P. Maybe add a bit more variation to the melody, too. But, I like it, man. Keep up the good work. :D
