Solid game music
As with your last track I reviewed I think this piece can stand on it's own however if you really wanted you could develop it further with a fuller orchestra so that it builds up to an even stronger and more epic climax. It depends on what you want out of the track, it's good as it is or you could use it as a foundation to build something really dramatic (maybe you could save that version for later in the game)
It's very different to the calmer piano pieces you make, which shows that you can diversify and create different moods. Keep up the good work!
