I like it! It has a clear and neat melody and the instruments you used are also pretty fitting for the theme. However, I think it is a bit monotone if that makes sense? Maybe thats just me... It also could've been more epic/broader imo. Still pretty heroic though.
And something pretty subjective: I didn't like the up-and-down xylophone (I think?) in the beginning, sounds a bit goofy to me.
All in all pretty nice though!
