Is the catwalk allways the same? And if why does it newer change?

When model walk they always have amazing posture. anda need to keep your head up as if someone wuz pulling u straight up with a string. U also have to have attitude. So the 3 most important thing to remember when ur walking down a landasan terbang, landasan pacu is 1.) posture, 2.) attitude, 3.)timming and rythem!
