Nicest work on your loosest and larger lines of action, Roadkill Soup, so keep going further and further and furthest.
But however, I'm not getting enough of the strongest, broadest strokes in your lines of action yet. How would you like to do another 1 hour of 30 second sketches of attitudes? (120 attitudes) The reason is because, if your first goal is to get better at making your sketches the most fluid as possible, then I would like to encourage yourself to do that. For more information, please look into a digital copy on Archive on Nick Meglin's Drawing from Within. This book has a lot of really swell drawing exercises, too.
Hope you'll find this helpful, nicer, and encouraging.
