Good job on your first video. I like that you keep it high-energy. However, most of your energy is coming from the shooting; I think your edit could benefit with a little more zip.
My main concern, though, is that you really gotta get control of that camera. For example, the handheld "dolly-in" shots are fun to shoot, but they don't look too hot, especially in fast-motion. Also, the coloring is weird.
I feel like you'd really benefit from using a tripod. And keep your hands off that zoom button!
I like that you're keeping things fun. Don't change that.
