I love the way she owned the stage.
I love her cleanliness and crispiness in the tone, and how lyrical when need be. No need to mention that she's technically superb.
I love that she didn't spend her energy
I love how she totally synched with the orchestra - not only rhythm-wise, but tone, phrasing and all. They sound like one body, not disjointed, unrelated performers doing their own parts.
Well, the last point is really unrelated to the music and it's really quite mean, but it keeps whirling in my head. She should tone her arms a bit... or at least find a dress that fits better. And, please, don't tuck the dress on stage. We, the audience, really don't need to see that.
After all, a professional pianist is a performer, in both visual and audio means. The look completes the "package".
