The title is a very good description of this piece. Got some great accentuations here. The build up for the intro was just right and lead in to your next phrase very well.
Through from there onward is all build up - strings on top of strings, your brass hits and your percussion give that marching kind of feel. There's no "real climax" signifying that the transformation has occurred - though I could see this since the mood changed at 2:00.
I still think you should have another phrase where it's highly bombastic, 'cause what this is missing some cymbal work. Make full use of your orchestration.
Composition is great. I've got no complaints since I love cinematic pieces. Quality is top notch, gotta say. A great job!
