Not to bad of a mix
You set a good intensity with your strings. Kick has a nice transient. Snare is punchy which is even better!
The weird effect was trippy, but enjoyable.

Things I didn't like was that it was the same groove and didn't have a real A - B progression, even though you added instruments towards the end, to make it sound "epic" it gets repetitive. Also try adding brass! Brass really adds to the intensity. Especially those french horns, they give a nice warm sound. Or if you don't want to do that, make the choir stand out more in front of the mix with some compression and EQing & automation
Also that the track just cut out with no real ending??
