Nice, and accessible pieces by Chopin:
A minor Waltz Op. Post, number 19 I think.
B minor Waltz Op. 69 No. 2, and imo Op. 69 No. 1 is a little bit more challenging but it's still doable.
E flat major Waltz No. 18, I think
A little bit more challenging:
Mazurka Op. 24 No. 1
B minor Prelude Op. 28
Cantabile in B flat
G minor Polonaise, Op. Post
Liadov:
Prelude Op. 39 No. 2 Cminor
Prelude Op. 46 No. 3 Eminor
Prelude Op. 40 No. 3 D minor
Musical snuff box, in A major
Schubert:
Landler Op. 171, the first five ones are really beautiful
i think it goes like, d major, d major, b minor, b minor, and b minor. Not sure haven't played them in awhile and if you play them together they go really well with each other.
Musical Moment in D major, idk which D number or Opus number though. Schubert wrote a lot!
You can also take a look at Burgmuller's pieces, he composed a lot of music for beginning and intermediate students. Since you've been playing for two years I guess you can also look at Heller's progressive etudes. There are some beauties in there and you can just pick the ones you want to play. If you want some more let me know, okay? Okay!
