Overall, sounds pretty epic, I like it! One thing I noticed was that it escalated pretty quickly, despite being a preview. I'd recommend adding a few more bars to the intro, maybe starting off with a solo violin, then add in the chorus violin. With orchestral stuff, rising tension is key to get a larger impact, so theres something you can try out. Aside from that, it seems like a good start. Definitely update your post when you've got the drop figured out, because i'd like to check it out!
