I couldn't help but think, this melody is too harsh. It is like a banging sound to the melody. There also seems to be no pedal. The stingy rubato makes the playing seem mechanical too.
My criticism is based on my personal feeling that too many young artists are getting overexposed to recordings and videos and trying to put those showy bits into their playing too soon--often at the expense of much more important aspects. Many of these affectations have to grow over time out of a total understanding of the piece.
