The markers look for originality in ORMs, but thats not saying they arent looking for quality lol. A&C has lot in common with Gladiator, most people have seen it, its easy to do, and hence a shitload of people end up doing it. As long as your answer is absolutely fucking brilliant, then dont do it, cos the markers will jus tbe thinking "oh here we go again, another gladiator one", when theyve been marking for ages in the hall etc
I dont know much about Elizabeth, but AF is pretty darn common. Just check those vids out, theyre pretty easy to do. Show your teacher, get feedback etc. You got ages to the HSC
