Hello! First time on the forum here!
It looks like a great program so far, but I'd be cautious with Beethoven Pathetique and Chopin 25/11; they're both famous pieces so try to stand out with those. I like the idea of Ellington, I don't know anyone who has walked into an audition with that.
For your romantic work, I would choose something more lyrical and light since Pathetique and Chopin already have a heavy texture. Schumann's Abegg is a great piece. Mendelssohn's Rondo Capriccioso is very beautiful and one of my favourites. It's a bit shorter than Abegg but I think they would be around the same difficulty. But at the end of the day, choose a piece that you enjoy, you'll be more motivated and the experience will be more gratifying

By the way, how far are you from your audition date? If you don't have a lot of time to learn a new piece and polish it, you could also pull out something from your previous repertoire for your romantic requirement.
