Great choice of repertoire! I agree with other people on pedaling, and I am wondering if your piano is actually out of tune. I remember my childhood old Kawai upright had a horrible cranky pedaling and it was like awesome_o says no matter how you try, my pedal moved like on and off switch, and particularly when the piano is out of tune the pedal will make all the sounds vibrate with each other like the way your piano does. Your bass notes do sound out of tune to me, though I don't have good ears.
Piano is a percussion instrument but it is not exactly the same with things like timpani. Not sure why I am talking about this, but your playing made me want to think about what it means for piano to be a percussion instrument. Anyway, you seem to like repertoires that require certain tonality based on all other posts you made, but the way you strike keys don't seem to go well with those sounds you like, so you may want to experiment more.
