I like your recital overall, but have a few suggestions about the "other romantic" and "twentieth century" works.
As for other Romantic, I would advise specifically against another etude. You're already playing two (the Chopin ones), so something a bit larger in scale would probably be better, especially for a masters' recital. I would suggest perhaps Chopin's Ballade #4, it's great music that would definitely show maturity.
The twentieth century is my favorite era in music-there's so much great stuff. How much time do you have? Here are a number of very challenging, highly musical twentieth century works (all would reasonably familiar to a panel, I think)
Bartok-Allegro Barbaro, Sonata
Prokofiev-
Sonata #3-virtuosic, a well balanced piece that's relatively short
Sonata #4-less commonly played, a great piece of music
Sonata #8-the greatest Prokofiev sonata, in my opinion. Long, and musically difficult, but a profound piece
Berg's Sonata no. 1 is very passionate, an amazing piece of music. If you really want virtuosity, you can play the Barber Sonata, op. 26. Scriabin also wrote some works you could look into (Vers la Flamme, Fantaisie, 10 sonatas, etc.). For contemporary music-there's so much. There's Ligeti with his etudes and Musica Ricercata. Rautavaara wrote some interesting pieces. I have an affinity for the music of Violette, but the panel probably wouldn't be familiar with it.
All in all, however, I would suggest you stay with a fairly familiar twentieth century work for your performance. Any Prokofiev, Bartok, or Scriabin would work well.
