I apologize for any confusion, but it seems like there might be a misunderstanding in your request. It appears that you're trying to use some parameters (--c 7, --w 768, --h 768) in your prompt, but these parameters don't correspond to any recognizable commands or instructions in the context of describing a girl.

If you could provide more context or clarify your request, I'd be happy to help you write a description of a girl or assist with any other writing needs you may have.
