Nice job!Two things I'd consider if I were you:Pedaling is a bit clumsy; many harmonies are unfortunately blurred. More clarity of tone is needed. Rhythmically, you play it more like a waltz than a mazurka. The second beat has much more significance in the latter. As a general rule, a waltz goes "ONE two three, ONE two three", and in a mazurka, there is the feeling of "one TWO three, one TWO three".Play around with these things, and you'll sound dapper.
