Your structure and grammar is fine, except you use the words ''American'' and 'British' as if they are languages. I am assuming you mean American English and British English. Both U.S.A. and Britain hold English as their standard language, but sometimes they are separated as such because of different terms and slang that are not common in both natives vocabulary. Basically, I suggest using "English" when you are referring to the general language and either "American English" or "British English" when referring to the individuals.

NB You hone something rather than 'hone on': I need to hone my grammar.
