Very very well done!!
I played this piece last year and will probably pick it up again sooner or later for a competition. However I found it just slightly fast, (IMO)... maybe just a little slower? Just to capture the true character of the piece (I'm not saying you didnt, in any way, just maybe calm it down a little, cos its a very calm piece, no need to race)
I really enjoyed it. As gaer said, its rare that incredible performers put on an amazing concert but you managed... what concert was that anyway? The audience didnt exactly seem too interested... hmmm.
