I was going for a video game intro screen with that last gen. I'm glad you like it! It's hard to believe what you can do with a simple text prompt now.
I'm not sure I should take credit for the looping idea because there is a node in base comfy now that has start and end frames as input options for wan. I imagine that's what they are there for.
With your sketches as a base you can get gens that you couldn't prompt for. Can you generate continually while you draw with auto-queue on?
