Help with new repertoire

[joaosousa]

Hey,

I would like to learn new repertoire mainly because I'm considering a career as a pianist and I haven't played any russian piece besides a Shostakovich prelude...

I would love to play some of Rachmaninoff or Prokofiev (or similar composers) work.

I'm currently playing:

-Beethoven Sonata No. 6 (op.10 n.2)
-Bach three part invention no. 10 (BWV 796)
-Czerny étude op.299 no. 39
-Chopin Polonaise op. 40 no. 2

Can you give me some suggestions? (Have in attention the difficulty)

Thank you.
