A few suggestions to your video:
- Use a video stabilizing software. The clip is shaky (unavoidable since it was taken handheld), when I viewed it in full screen I felt dizzy. It'll be nicer if you use a tripod or monopod.
- The time for a static scene is usually 3 seconds or less.
- Use a longer background music, or start a new one after one ends. Better not to repeat a short one over and over.

Look forward to your more great video!
