Hmm...
Look at my review for the first one, I have almost the same suggestions. This one just seemed too steady like the other one and needed some changes to the tempo and some fast instruments to come in before the 30 second mark to make it more "epic".
Maybe try a 3rd? You could make it better than ever. Maybe start off fast and give it an awesome intro like the song Danger Ahead by ParagonX9.
Still, good job, make more! The more music on Newgrounds the better!
Thanks!
