Chopin-Nocturne in E minor Op72.1, This one is pretty much down, just need to smooth out the little runs a bit.
Mozart-Twinkle Twinkle Variations, I can play through all the variations except the last one. I only have about half of them memorized though, and the left hand trill one still trips me up sometimes.
Granados-Spanish Dance 5 'Andaluza', I hate that d*mn jump onto the B-major chord. It's so hard to land, and it completely ruins the piece if I don't get it perfect.
Schubert/Liszt-Auf dem Wasser zu Singen, This is one of the most beautiful pieces for piano in my opinion, but's it's fairly difficult for someone of my skill. I just started a few days ago, and I'm thinking that this'll take me a couple months to get down.
Potential Canidates for future pieces---
Schumann-Aufschwung I've learned the first couple pages of this piece, but then dropped it. I can't remember why though.

I really love the theme that the LH picks up while the RH does the 16th note runs.
Chopin-Mazurka in A minor Op17.4 Half my repertoire is Chopin. I seriously have an addiction.

meh, it's just that all the other composer's piano pieces that I enjoy are too technically difficult. Chopin writes great simple music.
Finishing:
Rach's Corelli Variations
Scriabin's Nocturne for the Left Hand
Beethoven's "Rage over a Lost Penny"
How hard did you find that one to be? I want to learn a LH piece sometime, and that Nocturne looks like a good possiblity
