thanks,
i think i would critisize the same things as you when i hear (and see) the video 
the piano part sounds very boring on it..
but when i play it i really don't know what i should improve. only the wrong notes..
in my eyes it has much colour and a singing character.. you have to imagine i play it on a wonderful steinway.
i did and it was fantastic..
now don't think i am arrogant 
nevertheless i will record it again with a better mic ( i hope)!
Nice job, although I did not like it at all. Before I give you some ideas I should disclose I think such a superb artist as Martha Argerich doesn't play this piece the way I like it, so you are in good company.
Your pedaling does not follow either the melody nor the harmony, hence the blurryness.
it may be the piano, or the recording, but I find the touch percussive and monochromatic. One way to expand your color palette is to pratice at various attack speeds. Note I am not talking about a slower tempo, but just depressing the keys slower (and therefore earlier). Also vary the part of the finger involved in touching the key, and how the weight of the arm either floats or gets poured onto the keyboard. If you don't like Arrau, this probably makes no sense for you, but that's the way I explore these things.
I find no sense in the long pause between the A and the B sections. if you have read no E.T.A. Hoffman, please do.
Keep loving the piano and ignore what gets in your way to enjoy what you are doing.
