This one is really good.
Yay for battle music!
The first thing that came to mind for me, was make that begining part faster, I'm going to go as far as pretty much double the tempo there. I am however assuming too much, so please, if that is not the kind of battle you want going on (like Zroi Mai Grawd, just kill KILL KILLL!), then I wouldn't do what I just said.
This battle music you give us, is one filled with a strugglers journey, that constant timpini gives the air of continuation, and when it speeds up, it adds a neat level of excitement.
I would add another octave on those brass instruments, down one, from what you have now. Perhaps even make the original go down one, because that would give a much darker mood... again, I am assuming however, as it stands, this is a more final fantasy normal battle theme, and if this is what you wanted, you have completely perfected it.
I just like to throw suggestions ^^.
5/5 from me again Atomic. Keep them coming.
