First off, best of luck with the competition. Just practice loads and my piano teacher always said to me to perform your pieces to as many people as possible before the competition/exam - using this technique you get used to performing them in public. Doesn't matter who it is (family, friends etc).
My only real bit of advice is about your choice of pieces. Both are truly terrific and take skill to play well, however they are both arguably some of the most famous and universally played pieces in the piano literature. I only say this as the judges will have heard these pieces countless times throughout their career. Why don't you change at least one of them for a lesser-known/played work? By doing so shows a wider repertoire and you'll be more memorable to the judges if you played something that's less (hate to say it) overplayed.
Like I said, nothing wrong with your choice and just a bit of honest advice.
