Nice job on your quick sketches, Dorthea2410! You're on the right track on capturing figures as wholes! (or a whole)
Well, if I could provide you a sincere critique, it could be this: I love the motion and animation in those poses, but I really need to see more and more of them in your next post. Why don't you please go for 140 minutes of 29 second quick attitudes????? (140 x 60, 8400/29=about 290 figure cartoons, all flipped horizontally and/or vertically)
The reason why you could and should do this great advice is because, it's because it could and would, help you out on thinking visually in your sketches quickly. For more info, look up two volumes of the Walt Stantchfield books, Drawn to Life, on Book or Kindle, on Amazon.com. https://www.amazon.com/Drawn-Life-Classes-Stanchfield-Lectures/dp/0240810961 https://www.amazon.com/Drawn-Life-Classes-Stanchfield-Lectures/dp/0240811070
Good luck to you from me, and I hope you'll find this completely and totally informative, helpful, and encouraging.
