For sake of comparison...and in this case a mark of consistency I put the readings of these pieces from a concert at a health center/nursing home.
Now, what we have above are comments I very much appreciate from two new members. Shaggyy and Onwan, welcome to pianostreet. I can already tell you have much to contribute. Also to both of you, do not worry. Your English is much better than you give credit!
Ah, I am left in a predicament, for the time of these pieces has come and gone. They were both specific requests for a wedding, so I played them the day I recorded them, the day of the wedding, and then as a part of a little concert for a health center/nursing home, and that's about the extent of my involvement with them. Now, since I generally have so little time to practice, I'm having to be very specific in what I need to accomplish in practice, and so I have no real plans for these two pieces at present. However I got interested in Onwan's comments and a possible project:
I'll talk only about The nocturne because I'm learning this piece right now, so I'll be maybe a lot of critical. But if you want to hear true of interpretation (my personal and my teacher) this is it!
1) forgive my english.
2) the second note G it has to be played little bit slower and softly.
3) your left hand is so loud. I mean the basses are good but U-PA-PA (the pa-pa play quietly)
4) next think is, finish every phrase (everywhere ended ligature)
5) in 4th measure (Bb,D,C,Bb,Ab,G,Ab,C,D,E) slow down...a lot! there ends the firs part of piece. The first part play slower and quietly (1-4 measure) then you can be little bit faster and louder, but be calm!
ou, it is only a part of work...if you want, I can complete it like this whole piece, but I don't want to write it If you aren't interested.
good luck 
Onwan, since you are learning this piece. What if you...
1) continued with your thoughts on the rest of the piece and
2) I attempted to put your direction into action and uploaded the results in this thread?
Do you think that would benefit your own practice of the piece and interpretive decisions? From the teaching and experimental standpoint, I see many ways in which this could be helpful to me. What do you think? The only problem really is a time gap if I'm not able to immediately address your thoughts at the piano.
A parting word on the Chopin seeing as both Shaggyy and Onwan mentioned the tempo as quick...Yes it is quick in terms of modern performance practice. However if the metronome indication is to be trusted at all, the edition I used has a marking of 1/8 = 132. Actually, I don't think I actually approached 132 in either performance here...however, keeping the marking in mind I tried to feel the flow of the piece and some variety and contrasts within a quicker framework. That at least gives you an idea of where I was coming from, for better or worse.
Thanks for listening and commenting!
