What to play next?

Hey! Im wondering what repertoire i should play next as my teacher told me that i should try and find something to suggest.

To give you a view of my "level" last and this year i've played the Mozart violin sonata in g major, all of Sibelius op. 78, Telemann fantasie No. 1, Kabalevsky improvisation, Sibelius Novellette, Kreisler prelude and allegro and de falla suite populaire Espagnole. Also played the Kodaly op. 7 duo (first movement) with my friend

Im looking for some smaller pieces like maybe Sibelius op. 81 and then some bigger pieces like sonatas or maybe concertos? Considered that also maybe the Telemann 7th fantasie could be good. What do you guys think/suggest?
