Adding emphasis?

Hey folks, new to sexy ai, and really liking the tools. It's very powerful and a lot of fun, but I am having a hard time adding specific emphasis to certain prompts. I came from another service that used colons and a rating scale up to 1.5. E.G. (big boobs:1.5) if I wanted to give my models huge oversized boobs. Right now I am adding more brackets and words ((((big boobs)))) to try and add emphasis to the prompts. Is there a better way to add more "weight" to a certain descriptor in a prompt? Pic for fun for the current project Thank you!
