You would not see me sitting like that, every. Roll chair, normal chair ... ouch! No!
My daughter will love this photo, too (though on Monday she went to her last ballet class ever, she stops going there now, too much swimming, too little time for dancing).
Excellent photography. I believe that to make photographies of a personage in its surroundings a success on the part of the photographer is everything. Good work.
