Don't over-edit the vocabulary in the letter or try to get too clever with phrasing. You want to communicate that you can write, so make sure the letter is grammatically correct and well written, but if you find yourself going to the thesaurus to find "the right word" you're taking it too far. Keep it simple, be polite and use proper grammar and you'll be fine.
