Thank you for your comments.
I like the narrative gesture you put in general to this Sonata; by this I mean e.g. the opening when you take up slowly the pulse or the simple/noble sound you play the melody of the end of the exposition (b.136).
(1) You do not keep a steady pulse throughout the movement. Whenever there are more than two quavers to be played, you speed up, especially in bars 48 f. and 183 f. (201!). This leads to an unpleasant tempo-shift in the repetition of the exposition and to a hasty impression at the questionable passages.
I disagree. I think my overall pulse is quite steady. I don't think an overall tempo needs to be completely
straightjacketed in a composer like Beethoven (this particular movement being broken down into several sections), whom I see as at the forefront of romantic music; that would be unimaginative. When I apply slight shifts in tempo, it is quite intentional. Whether you agree with it or not is a different matter.
(2) The balance between the melody and the accompanying quavers could be better (quavers softer, melody with more contour).
(3) A comparatively small problem: Sometimes transitions between single notes or bars seem to be a little clumsy: e.g. the quavers in bar 4 and similar places (the last one a little to short and loud, to my ears) or the octaves from bar 29 on; maybe there you could use a better fingering (fingers 3, 4 and 5 for melody-legato?) or the pedal in an unobtrusive way.
Not sure what you mean here. I don't hear this.
(4) And ultimately a personal remark: I believe the sfz could be much stronger; especially in the beginning I missed them (I like he one in b. 165).
They sound quite strong to my ears.
Some thoughts about the recording: It's always difficult to get a nice sound in a small room. In your case, the room is clearly audible. Maybe you want a bigger sound, than this is what you could try: Try a relatively close microphone position and add reverb later; reduce the early reflections of the artificial reverb (you have enough in the recording) and try to find a good balance. I recorded the Janacek-Sonata (which can be found on ps) in a teaching room at the Musikhochschule Nuremberg as stated, maybe this can be a recording-inspiration.

Thanks for your thoughts about the recording setup.
