If you’re teaching yourself, then you’re doing very well. Good sound, good control of tempo.
A small mistake: In the fifth measure of the fifth line, you’re misreading the rhythm. The melody is three equal eighth notes—you’re playing two sixteenths followed by an eighth. That gives you a measure of 2/8 in a 3/8 waltz. (Of course you didn’t mean to do that.) And don’t overlook the da capo. The return to the beginning gives a nice symmetry to this piece.
I hope you can find yourself a good teacher. You’re obviously serious about this. (You’re doing better than I did when I was self-taught.) With the right instruction, I suspect you’d do great. And you’d have a great time doing it.
