Hi Dustin,
Your work is amazing! The melodies, chords, and instruments are great and epic !
I think you can improve more in the general mixing by example there is a strong moment with a crash cymbal and it's a bit shy compared to the level of the other instruments. There's a little lack of power during the epic moments, maybe you can try some staccatos or increase the volume of the low drum? (That's only suggestions and for maybe it can help you for your future works)
I think you are really talented, keep going!
