I'm also starting ESPS in September (or, next week even!!! :-) ) , with major language French. I also got, and met an AAA offer (French, History, English Lit or Maths).
Your grades seem good enough, but what might be a problem is that you studied no 'humanities' for A-level, which they explicitly ask for. And no, English Literature doesn't count as a 'humanities' subject, i asked that myself (but i also had History). On the other hand, you have an A in French, which should be a plus (even though you're doing Italian) since it shows your interest in foreign cultures/ability with languages.
Like chiller said, it is quite competitive. I really don't want to show off, but i got the 5 A's i was predicted and i also had an A in German, so it does seem that they are quite demanding. Since you have that problem of no humanities you're really going to need to impress them with your personal statement/interview. I put quite a heavy emphasis in mine on my international upbringing, 'European spirit' etc...although i don't know if that's what did the trick for me. I did have the feeling that they had already made their mind up by the time i went for the interview, so if you do impress them with your Personal Statement it might work.
I fell in love with this course from the start, and i really recommend applying-it's definitely worth trying and you certainly have a chance of getting in! All the best!
PS: there's quite a large thread on ESPS further back in this forum (something like page 8 or so) have a look for more tips...
