For the measures with the intricate voicing (2nd page), you can try some of these methods to interpret it.
First of all, playing the uppermost part extremely soft should be avoided as it is not only an accompaniement but also has a melody of its own. However, it should not overhaul the middle voice. That's the difficult part about it. Many pianists just play the upper part extremely soft for the middle voice to stand out, forgetting that the upper one is more than just accompaniement.
One more interesting thing to try out is to make the topmost note of the LEFT HAND accompaniement a little louder than the rest, making it mix a little with the middle voice. See if you like it. Personally, I do! Also, do not rush through this section (this applies to the whole piece, as well). I have, so far never found a recording(except for a very rare one by Irina Smorodinova) which does not rush through the piece. I complete it in about 4 and a half minutes as opposed to most others which do it in a little less than four mins.
Hope you like my suggestions!!
