This is me drawing along with the videos from this course on creature teacher:
It's a really great course! very simple and well explained!
Terribly copied from my end but for me it's the best ay to process information.
Some people just watch a video, but at least for me that doesn't stick. Best way is to watch it multiple times, draw along, draw it from memory, apply it to reference, and come back again next year to repeat it :D
