Very enjoyable performance (I listened twice)! You certainly have a good grasp of the emotional content of the piece. And the recording quality is just superb. So my comments are only minor and largely inspired by my own struggling with the Intermezzi...
I would agree that "a little more drama" would be desirable. But then, these pieces are very introvert and introspective, so it's a fine line and one can easily overdo. Thus, the nuances a very tiny ones (e.g. diminuendo from p to pp), which makes it a hard one. Apart from dynamics between adjacent notes, there is the dynamics between the melody notes (think e.g. in bars 1-8 ), and it's important to think about the whole line - where is the climax? where should I gradually tone down? Also, some notes could have a more "longing" feel, especially in the passages indicated "espressivo" - maybe try giving them a bit more weight (not necessarily loudness) with the arm. Also, I would try to get as much legato (from the fingers, in addition to pedalling) as possible. A good practice would be to play it completely without pedal. Together with a very fine-tuned dynamics it should support the flowing character of the piece. And then, I agree with Chris, from bar 67 on, after a whole time on p and pp, there's the first f indication, and more to follow. This climactic character should be audible, and also make a nice contrast between the legato lines (e.g. bar 73/74; these also need as much finger legato as possible) and the repeated allusion to the second melodical idea (chords). Btw, this second idea, which first appears in bar 22, sounds a tiny bit clumsy to me (really only a bit), and I guess the reason is the same as my problem in op.117/1: the hand plays full chords, but it should sound dolce, piano, and very legato. Again, these are minor comments to what is a really nice playing!! -Tobias.
P.S. I'm a big O'Reilly fan, too! Our institution has a Safari flatrate, so I'm using the books every day (and I love the animal covers!!)
