Hi caick,
At your level, I would solidify your playing technique first before going on to other crazy sorts of stuff.
Have you looked at
-Two-Part Inventions by J.S. Bach
-Sonatinas, Op.36 by M. Clementi
-Sonata in G Major, K.545 by W.A. Mozart
After you played some of those, I would move on to
-Chopin Valses, Op.64-1 and/or Op.69-1, 2
-Beethoven Sonata Op.49-1, 2, Op.79
Happy practicing,
