Well, I checked out your site, and while your music is pretty good, I've gotta ask: haven't you ever heard of modesty? Pimping your stuff out as THE BEST THING EVER is a huge turn-off.
To offer some actual feedback on this song, I like it, but I'm horrible at music critiques, so I don't have much else to say. It reminds me of Holst's "Mars", though.
Edit: Actually, I think it could use some more variation in the melody. I like the atmosphere, but it gets very samey after a while, especially for something you might hear every battle.
Edit x2: For example, the
Xenogears boss theme has this one cool soft part that does a lot for the piece by breaking up the tone for a second. I'm probably describing this really badly, but um, oh well. Listen to it and you get the idea, hopefully.
