I can only comment on the nocturne because it's the one I know.
-The rythm is all over the place

. This is extremely easy and tempting to do with Chopin because you get lost in the emotion but it's almost obnoxious to the listener. It's just very exhausting to listen.
Maybe this will change your mind on consistent rythm:
One of his students, Friederike Muller, wrote the following in her diary about Chopin's playing style:
His playing was always noble and beautiful; his tones sang, whether in full forte or softest piano. He took infinite pains to teach his pupils this legato, cantabile style of playing. His most severe criticism was "He—or she—does not know how to join two notes together." He also demanded the strictest adherence to rhythm. He hated all lingering and dragging, misplaced rubatos, as well as exaggerated ritardandos ... and it is precisely in this respect that people make such terrible errors in playing his works.
Otherwise, you definetly can pull it off! You have good technique and good tone, you just need a little extra confidence to iron out the mistakes in the difficult parts. You can do this by just playing them over and over and over again. Also, watch the phrasing. This is so crucial in Chopin. You seem to pop off the last note of every phrase, making it louder than the others, when in reality it should be much softer. Also, make sure that when you finish the B with that climbing g-minor arpeggio, you finish the sound before you take up the main theme! Right now you hold the pedal down through it and never give the audience a break.
And I can't stress the rythm enough. Especially the rushing >.<. That very last arpeggio, I'm waiting for for a soft, rit. finish, instead youc opmletely blasted through it leaving the end a little unsatisfying.
Although it may not seem like it from my comments, I do think you did a great job with it! You obviously have the skills to do it correctly. I think you need to confer with a teacher who knows about Chopin to be able to perform it even better, because it's very specific.
And don't give up and lose confidence!
