I was very interesting to hear you play this piece because, accidentally, right now I also start to learn this piece. Funny thing, accidentally, I also use Rode NT5 pair.
Investigating different positions I have never try your mic placement combination but I will try. (But, my problem is not mic, my nails are more frustrating,.... forget it,....). Yes, reverb is audible, but to me it is ok.
Piece is lovely and your interpretations and changes are original but at most of the time it is acceptable for me. The only thing that maybe is open question is duration of pause or stop. Because, this is waltz, dance - and we must think that one man and one girl must dance together at this waltz, with longer pause it is not easy, isn't it?
But, if you are in good mood with all of that, express yourself at your way. I am always curious to hear interpretations that offer something new.
So, good work, keep going,...
