Hey!
I'm a Stable Diffusion user myself, but I'm curious what MidJourney can achieve!
Myself I'm a fan of big hair, it doesn't even have to be very long, as long as it's big and super soft-looking. Also a fan of fur, so maybe a prompt like (feel free to add more to it/change it to get better results):
European woman wearing an oversized fur coat, big hair, brushed hair, sitting in a plane, playing with her hair
Something like that. The plane bit is random but it's a fun setting, adds to the imagination I guess.
Thanks in advance! If you want some other ideas feel free to ask, I've come up with some fun ones I think.
