The only difficult part is the closing runs, but Chopin 
sounds better when re-interpreted to suit your own 
style. Don't view this as a set-in-stone guide, but rather 
a reference. I add all sort of trills, runs, etc. to liven it 
up, because the guitar is only capable of playing the 
melody. The half notes get pretty boring if you don't do 
something with them. Basically, mess around with the 
song as long as the melody is still distinguishable.

If you do play the runs, don't do some over-distorted 
shred thing. On the piano, they are meant to be airy 
and delicate, not some harsh, abrasive technical 
display. If you can't play the runs softly, put in some 2 
beat fill instead.

By the way, if you can play that 35-tuplet run, you are 
officially a god in my book :-P .
