Just watch.
A cat animation I did in about less than 30 mins so I could film myself for a project. It's been a long while since I've really touched the bitmap editor or animated on Scratch. Not my best work (it needs one extra frame to ease it in) but I've definitely improved from my first animation, especially with drawing speed and my understanding of timing and spacing.
