The last display/waiting pose is almost correct but way too easy.
A well-trained slave should never be allowed to rest on her heels, but only on her tiptoes.
And (just for the fun) I would add something between her legs and in her mouth.
The pose must be kept for 60 to 100 minutes without moving or complaining. The penalty for each failure will be 15 extra cane strokes and 10 more minutes.
There's much room for improvements here (see pics):
