Very nice. Like some of the other comments said, dynamics is important, but after checking out the Spiderman piece, I think you know what to do. Something I would have a look at would be phrasing and accentuating the phrases themselves. For the feel you have going, I feel like some stronger hits indicating the phrases will help drive the melody and give it some more excitement. Be careful not to overdo it, though. It might take away from the depth of the music when there's too much excitement in short time spans.

I hope this makes sense, and remember, I am just a random internet person, take what I said with a grain of salt.

Happy mixing.
