This is a great piece of music. Like a ballade.
Notice the iambic pattern in the middle section, typical of a romantic rendition of what a ballade is supposed to sound like.
Chances are there is a programme to this music, although I have never heard what it may be.
Don't play it too fast and let it breathe. it is easier than what one may think upon reading it.
The 4 against 3 resolves itself if you play with lots of rubato. I recommend not lining them up as if it was one 8-note and two 16-notes. For me that solution is lame, even if approved of in a footnote.
Cheers.
