I hope to help you in the case of trouble in the pose of the illustration.
In addition, the box that comes out to the samune is not attached because only the right knee and the left hand are made to be able to understand the feeling that it is grounded on the surface of the box visually.
イラストのポーズで困った時にお役に立てれば幸いです。
なお、右ヒザと左手のヒラが箱の表面に接地してる感じを視覚的に分かるようにしただけなので、サムネに出てる箱は付属してません。
