Good mix. Maths always respected, a language always gives you an edge, and you're showing ability in essay writing with History (with a good mark). Those three subjects are all fairly academic, not just Maths.
English Language is fine, but the person above has a point (not as respected by universities, might get ignored or lower the impression on your application to uni). I'm not saying don't take it, just think about what type of university you'll want to apply to. If it does affect your application, it would only be on the top few universities in the country. So, if you don't think you'll be applying to places like Oxford or UCL or something, go ahead and ignore this and just take it. Additionally, you could take it and drop it after AS level.
