At my college we gave our PS to our personal tutor. She doesn't teach us anything so she isn't skewed towards one particular subject (if that makes sense) and could look at it objectively. Is that an option for you?
You're statement should have more about English in it as it seems (from your wording) English is the main subject you're applying for, with some English with Media courses? Give it to your English teacher and make sure your English section is as good as it can be. Then I would just integrate a bit of media throughout. But make sure, if English is the main subject, then the focus is on English because that's what your unis will be looking for - a passion for English.
Good luck!
