try not to fail notes, practice more slowly for that. Also, there's some chords that we don't hear, and the one we hear are too loud. Practice them without the other hand. Also some times you make too much noise. The Chords need to be the loudest notes, the rest wayyyyy less loud. for the chords, don't to staccatos, then legato. You need to chose. Use the pedal too, but just a bit and wisely.
