I thought it'd be fun, but apparently it's not as cool as speed up painting... Also I like how it looks like I'm doing a lot of stuff, but in reality 80% of times I'm just rewatching a video and playing with keyframes. c:

And btw I started with 4:3 aspect ratio, because I wanted to make it old commercial feeling. I'd add grayscale filter and stuff like that later. But then I realised how bad idea it was, so I switched to 16:9. That's the story.
