Two things became apparent to me within seconds of watching your performances. (Admittingly, I watched Jurassic Park before the Moonlight mvt1. I'm a sucker for John Williams music.)
1. You have musical talent. It could not be clearer.
2. You have some technique issues that prevent you from performing to the level that I instinctively believe you 'hear' the music.
I don't really have the time right now to do a full breakdown of your technique (it's 4am and I have to be at the airport in two hours), but you've got enough videos posted that, if you'd like, we can start a PM chain to discuss.
For now, I'll pick the top two:
1. Wrist height. Watch the opening of your Moonlight. Look at your left wrist compared to your right. Your right is more akin to "proper" height. Your left is way too low, and it causes a concave arching of your hand, which creates tension.
2. Stretching. Your fingers sometimes look uncomfortable, because you hold your hand open with your fingers spread out. Try this: drop your hand to your side as if you're just relaxing. Move your fingers as rapidly as possible. Should be no problem. Now, spread your fingers out as straight and wide as you can, like you're holding up a huge number "5". Move your fingers. You'll feel a ridiculous amount of stress and tension. The idea is to eliminate the second as much as possible, so you can move as fluidly as the first.
There are ways to do this, and I'd be happy to discuss it further. If you're interested, shoot me a PM. I say to PM me, because I don't want to bore everyone else in the forum with a long thread.
My one other critique: play more John Williams, please.
