Looks pretty good, I mean strong and very balanced in terms of style.
Do you have to do two Rachmaninoff Preludes (it's been ages since I checked the syllabus)? I might go for a more 20th Century composer in addition to just one Prelude, maybe Morton Gould's Boogie Woogie Etude to make it even more "diverse" - it'll be by a less known composer.
I like it though, it's really balanced, and I personally think it's fine
