I usually just start with a background, and animate it if I want to, and then I add the characters, and change their frames a couple time until I like the way it looks. Then, I add finishing touches. In this case, the lightsaber blade colors, and the dirt beneath the characters feet. Then I watch it a couple times to make sure ir’s good. The hardest part is animating the characters, so if I’m having trouble, I take a break. And that’s about it
