The chord voicing in the first has more depth and works better in the outer section, the middle section of the second has a more ethereal effect and works better ....
This is often seen as "easy" Chopin, but IMO is actually quite difficult to get right.
how do you get away from making the first 8 chords go "loud,loud,loud" ad nauseum?
By recognising that not all "loud"s are the same. There is a rhythm to keep, there are crescendos and decrescendos, though not large ones, and there is the different voicings you can do within the chords to add to the variety and emphasise different elements.
don't be scared of doing some truly horrible things - it's how one finds the boundaries.
I found this idea especially intriguing.sounds like fun, actually.
