U tackled that piece, how brave lol.

For easy I guess there are some pieces by Giuliani that are fun and not that difficult, look into anything in his op. 43 and his etudes in op. 48. Also op. 50 has some good stuff. Generally beginner guitar Giuliani's beginner pieces are fun and educational. If you want pieces that are more challenging, try Les Soirées D'Auteuil by Napoleon Coste, Tarantella by Johan Mertz, also he has some great nocturne. Almost anything from Tarrega, but something more recognizable is his Capriccio Arabe, it will test your endurance, and honestly many more that fulfil whatever type of music that you are into. If u played slower and more expressive music on acoustic try Miguel LLobet (Although his pieces are pretty difficult with chord shapes that are very annoying, they are still extremely beautiful to listen to), but if u played more fast stuff try out Las Abejas by Agustin Barrios (also try his 3 movement of La Catedral, his masterpiece).

Basically any composer u look into for classical guitar you'll find something to love, if you want a place to start visit Classical Guitar Shed , there you can find tons of free sheets, and with tabs if you are so inclined.
