Feedback please

I'm trying to extrapolate the pose of a clothed reference. But the proportions near her hidden leg seem very off to me. How do I fix that? It's supposed to bend backwards at the knee and then rest on the toes.

Also, does she look like she exists on the floating chair and floor tile? or does she look floaty?

Sorry for the poor contrast in pic, I used a hard pencil this time so I can easily work over it with a softer pencil once I'm satisfied with the body and pose.

Posting the ref after this post.

The jaw is not spaced from the lips and closes too abruptly like a prism on the bottom end. Also the right cheek (from the subject's view) looks bloated because it's supposed to be turned slightly away from the picture plane.

Same with the eyes, the line that connects the two should be a little slanted towards the horizon and the left eye(subject pov) should be bigger than the right due to foreshortening.

And the nose points straight out at the picture, it should be turned away.

Otherwise it's alright. Good job anon.
