I like the attitude in this pose, but it's a little off balance. I moved the right foot out a little and added some gesture to the legs. Also, think about having some perspective on the bottom of the cape. I hope this helps :)
the foot out already sells the attitude more, maybe let the cape hem tip with that same lean so the silhouette matches the new balance
I was kinda looking for more help with the design, but thank you for the info on the posing!
yeah the foot shift helps, maybe plant the weight on that front leg first so the cape hang follows one clear lean before you cut more folds
