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!
