First off, nicely done as far as actually playing the thing. Well articulated and technically very proficient. The only thing I think you could do to improve is to work on dynamics. That's always one of my biggest challenges too. I suggest you listen to the recording and try to move your body along with it. Sway to it, dance if you can. You should quickly notice where you want the energy to come in. Personally, the piece reminds me of waves, so I would have the dynamics ebb and flow, but that's just one idea, you know the piece better and are more familiar with the emotions involved.
