Chopin's Nocturne Op.72 No.1

[kekepania]

I am currently learning this piece. I am grade 2, (I've been playing for a little over a year), but I can play pieces that are beyond my grade. I've already learnt how to play Nocturne in C# Minor, Nocturne in B flate Op.9 No.1, The first movement of Moonlight Sonata, and the "Raindrop" Prelude, along with a few other pieces. I am trying to tackle this piece and I was wondering if anyone here has any tips on how to play it because I have quite small fingers, I don't think they've grown out all the way (I'm 16.) Thank you for any help, for it is appreciated.
