A lot of potential
I agree with a lot of the feedback below. You show tremendous potential. In the non organic animations, there is a lot a of detail: Helicopters, airplanes, guns, cameras. When it comes to people, they are stick animation. I would say to test yourself and explore the animation of organisms and the anatomy of people. Explore your style and make the people match the surroundings from an animation stand point. Great work. Keep growing. Don't get stagnant.
