The model would walk on that.
If the model was a dancer, even an amateur dancer, that would be great.
A catwalk makes it easier to do funny walks and eccentric dancing.
There's no end of funny walks.
Some walks and dances look better when more than one dancer does them. No problem. You just sketch in the clones after class.
Two models can become eight, as in this dance of Fosse's: The Rich Man's Frug."
Or one man becomes three. The choreography for a session like this could be improvised or planned. Me, I'd love to think of moves for sidemen to do.
Poses involving animals like horses are no problem. You draw the model-driven rider poses then add the cartoony horses later.
If you had two models doing different walks at the same time you could combine the drawings in a sort of collage.
Remember to bring some tape.
