Assuming it leans BBC, you would want to nominate it in the home thread for that. Just be sure to read the opening post to make sure AoT fits the requirements (there are some length limits and such), and copy the nomination template so that everything is formatted correctly. 
Checking the Natively level, it is 29, so it may end up on the upper end of that club, but when you nominate, you put in some example pages, so the club will be able to judge the difficulty from that. If it is a bit too difficult, they will just suggest you nominate it in the Intermediate Club instead. You can cross that bridge when you come to it, though.
