Very good. Really.

A little tip for those octaves: I know many teachers advocate bouncing via the wrist, and that will hurt and there won't be any power. The way you're doing it, however, will not give you accuracy, note-wise and rhythmically. It will be better if you don't bounce up THAT high off the keys. Move horizontally, not vertically.

Actually, after looking at what you do, you need to avoid hitting the keys from the air. Totally. Start from the surface. That'll affect accuracy and sound. You don't want to bash the piano - this is the Heroic Polonaise, not the Panzer Polonaise! And all that arm-lifting towards the end is really unnecessary to the music. And you are sitting too high. Way too high. This contributes to the bashing that you do.

You may also find the introduction more comfortable if you sit lower and play the notes from the surface. That and the LH octaves are really the only spots that don't sound as good as everything else.
