Cosplay ideas, would mind some outside ideas/opinions

Hello everyone, I'm planning to make a cosplay for Hunt showdown and I need help deciding some stuff to make it feel more well... hunt showdown 🤣😂

I'm planning to do one of the following Redshirt, Post Malone (not ringleader), Phantom/Royal Phantom or lastly my own personal character idea which will be a mix between a plague doctor and steampunk (so basically a steampunk plague doctor

Basically I would like some advice on what I should do or things I should try in order to make what I am doing work, any advice would be appreciated
