Nice animation! The art / animation is a little rough around the edges at times, but the overall camera angles, sense of action, and movement are very good. Work on the contrast of text / titles - for instance, add a black slightly transparent background behind the subtitles, and it would look much better / make the text pop more. You could even add a simple button to show / hide the subtitles, which would be a nice touch.
Also, great use of my song "Shifting Sands". I pictured a desert when I made it, and it was really cool to see it used in exactly that way. Keep up the good work, you'll only get better as you go :)
