Translation of appraisement in German

I want to improve my level of English. Have you ever been in the U.S. and in which states have you been? I've been in England, Scotland and Ireland, but unfortunately, I have never been to America.
As mentioned in our conversation, I will send a more detailed description about all the other exercises. As indicated previously, I believe in your technical skills and in your talent.
What do you think of the current situation? Like you, I am writing letters, emails and other messages. Tomorrow I will leave, then I will go to my friend in Spain, where we are planing a beach vacation.
