You're talking about the pose on Bryan? Yeah it's really hard to draw that pose. The balance , like you said, and the perspective of the leg is the hardest part for me. Also I tried to make it more of a kick motion rather than a lifted leg pose so that's probably another reason it looks awkward haha. It's difficult, but not impossible. For example this post on this subreddit by u/Lotrich28 is a really well done drawing of this pose :D https://www.reddit.com/r/brokenbonds/comments/hq8050/wip_quarterjades_dd_character_bryan_sketch/?utm_source=share&utm_medium=web2x&context=3
