just one more thing I forgot to mention.
walk a little slower... and think about your breathing as you enter--simply to clear your mind.
you were already imagining yourself at the piano as your walked in... and you weren't "there" in the present.
I used to tell my students to pause at the crux of the piano and give the audience a big smile while thinking
"thank you for letting me play today..." think about smiling with your eyes, too.
let them get a good look at your face---before and after you play. look just slightly to the left and to the right and give them maybe a hint of a nod....another smile... then walk to the bench.
You want to do this especially at a competition because they are already forming opinions about you from the second you walk on stage. ooooze confidence--even when you're scared to death.
if you appear uncomfortable in any way--the audience will pick right up on that and they too will feel uncomfortable.. there is nothing worse than seeing a player look afraid--then you just wait for them to cake.. you know it's coming....you don't want to watch...but..you do...you want to cover your ears but you don't...and if you know the piece and where the problem areas are...then you know right when to listen for the flubs. You are poised to cringe in pain when they stumble--and you are waiting to hear mistakes instead of listening to the performance.
sometimes you form an opinion before they even get to the stage... you see them walking around crying, or shaking from nerves, or throwing diva fits 2 hours beforehand... you wait for the disaster when you see them walking on stage...
you NEVER want to make your audience feel that way... which you didn't ---I am just illustrating a point...

never let them see you sweat.
project confidence throughout the performance--and not just your playing--in every single thing you do from the time you get to the competition... until you are back in your hotel room.
then you can scream, cry, eat ice cream, fight with your boyfriend, talk on the phone... whatever you do to wind down after playing.
