Favorite flashy clical piano works?

Hi I'm 13 and grade 7-8 piano so Chopin's �tude Op 25 No 9 (erfly �tude) is the best, flashiest piano piece I have ever heard/learnt it's only 3 pages but if u can master it (like me XD) then yer that'll blow people away it's very fast but u don't have to play it that fast for it to sound impressive and it's relatively easy/quick to learn if u spend some time on it it's roughly about a minute long. Hope I could help :)
