SAQ Cambridge Personal Statement help?

I'm applying for English and was wondering what other applicants are including in the additional personal statement?

I wanted to mention more information about why the course appealed to me - I'm Russian so I mentioned how the idea of being able to combine the study of foreign language alongside literature interested me. I did briefly mention my heritage and love of Russian Lit in my UCAS PS, so is it okay that I included extra info about that in the SAQ also? I also mentioned in my UCAS PS that I'm a performer but didn't have space to talk about much of my Drama studies and experience, so I wanted to delve further into that. Do those sound like good things to include? I know admission tutors say that they'd rather applicants leave the box empty than waffle, so I wanna make sure that what I plan to say is what they're looking for in a SAQ PS.
