Is still not possible to create two different looking people in the same image? (With 1.5)

Hey... looking for some guidance on how I can write a prompt in a way to portray two people in the same image with differing physical characteristics, (if it's even possible). Maybe it's more straightforward on more advanced models like Flux (or whatever), but using SD 1.5 every time I try they end up looking like virtual twins. If they're is some sort of syntax I'm not aware of to accomplish this I would love to know. Any help would be greatly appreciated. Ideally, to just inform the program that I want two different looking people without having to describe each in detail, but I'll take whatever guidance you might have. Thanks.
