I love this piece! I makes an orchestral piece sound huge and epic, but at the same time, keeping it modern, like maybe a video game theme.
The only thing i would like to critique is that the drum kit sounds a bit out of place. (not much, but just barely noticeable) I think you should use less clicks and maybe a bit more bass to fill those empty spots.
I am not an expert on music or all that, but I just wanted to comment telling you how great of a job you did with this work of art.
