First Draft of Cube - Feedback please

I've finally managed to do it! I got 8 people together and tommorrow we'll draft my cube for the first time. I'm very excited. Been following the sub for a while now and been thinking about building and changing the cube far too much.

This is my cube: https://cubecobra.com/cube/list/5ed1d9d9-8614-4c05-bcf4-d12ad1b91f75#

Since I have no experience with building cubes and balancing I'm concerned that there might be imbalances, power outliers or maybe cards that go nowhere. Could you please take a quick look and tell me if there are some complete power outliers or glaring imbalances? I appreciate any feedback and just wanna thank everyone for the great input and getting me into the bestest mtg format there is.
