I played really well, but
Yohan,
First I'd like to say that you are a good pianist.
I do want to ask you to define a couple of things:
- What did you want to say with the Mozart? How do you feel that piece?
- What did you want to say with the Chopin? How do you feel that piece?
While admitting that YouTube video clips are too poor as a medium to actually transmit anything deeper than superficial visual and audio impulses, I don't feel the cultural and emotional connection enough between what I expect and what you play.
Nobody at a competition is really interested in
- how difficult the pieces are you play or
- whether you miss or don't miss certain notes occasionally;
- how loud, how soft, how fast, etc. you can play, and whether you do that in exactly the right places;
- how you look, move, etc. while playing etc.
You have to tell people something in their own "language" with their "idioms" so to speak. That's what earns you a first prize in a competition, and nothing else. Instead of blaming the judge, think of what went wrong in the communication. Why didn't she "understand" you? ("didn't like" is your impression, but I cannot believe that to be true). The answer to those questions will greatly boost your development.
EDIT: I also miss the psychological pressure you are supposed to put upon the audience: "Here I am, and I have something to say. Take it or leave it." Trying to meet all of somebody else's expectations in all respects is your enemy in art. This is something all good artists in any field realize. This attitude is necessary to avoid the listener getting the impression that you are merely citing "a learned lesson" up to known standards.
Good luck!
