Replying to First Showreel, Please Critique

Hey guys, I've been working on a showreel for a little while to give to businesses instead of showing them a bunch of videos I've made. I'm sure there will be a ton of stuff which can improved before I have it perfect, so a quick look from anyone is greatly appreciated.
