I like your artwork and that's why I'm kinda sad about this reel (I know, it's not actually a demo reel, but it's still a collection of your work).
It's simply a bit too fast, you've done so many great animations, I would recommend to show them a bit longer, 1:30 minutes or so is still short and people who are unfamiliar with your submissions will learn more about you. And you deserve it, your talent for pixel art is obvious!
