Bad quality, but in art class. I used Line of action, or https://line-of-action.com/ but please credit my sister, @Dahliia- who shared it with me! This took as long as one period, or 40 minutes! The cat on the rocks took me the longest, but I used five minutes to draw them each, some when I got a rough sketch, skipped to the next picture.
Line of Action gives you references, but I did not copy them. I'm interested now in birds and hooved animals, as you might be able to tell. You can also draw humans there, so go check it out! It's really helpful!
