A Good start!
You've got a lot of good material here, so kudos. Some of your instruments are clipping. For instance, when you have a lot repeated cymbal hits there is some distorting going on. I'd bring back the cymbals just a bit, and keep an ear open to unwanted distortion. Here's a tip: Try using cymbals to finish up drum fills. It will make the piece flow much better.
I think your main issue is with sound levels of the instruments. Try going in with a critical ear and readjust the volumes. The Kick drum should be a bit deeper and not quite as wide (it's causing some of the distorting). Also, try toying with the idea of adding in a bridge for some variation!
All in all, nice work. Keep working at it!
5/5
