Your playing sounds very solid to me. Well done.
I suppose, it could be a bit faster, if you can manage it. You do speed up a bit the first time you play the second section, but to me, that sounds like a nice tempo to play the piece. So, perhaps you could play the whole piece to match that tempo, (apart from the last line). Generally, you should play it more rhythmically too.
You could also work on your dynamics, by playing more loudly in places, particularly in the second section, so it would sound more dramatic. You could also accent some notes, perhaps the B in the second bar of the second section, because that is a dissonant note, which resolves upwards to the C. Think of that phrase as lively!
You could also play the last line more softly, to go along with your piu lento.
Anyway, good job!
