The composition on this is quite excellent. My complaint would be that once the orchestral instruments come in, the drums and bass are buried. Save this project, come back, and revisit it.
You could probably benefit from sending a quiet file like this to a mastering engine of some sort, perhaps having someone draw out the percussion and bass for you via another program first. I could actually do that for you, and perhaps reduce some of the reverb that's taking over the piece.
Those arps toward the end are quite masterful though. I'd say on the compositional end, you're far exceeding what software you have. Those short staccato trumpets and bones might do well with a facelift using musescore soundfonts, if you can figure out how to use them.
Can't wait to see what you come up with next :)
