I feel like I have the consistent problem of drawing the OUTLINE and not the GESTURE, ...or essence of movement. But if I do just lines they turn out very stickfigure-y. I feel like im so bad at exaggerating angles jussst right. I also have a proportion issue but I feel like that will improve with practice. Thank you!
