Little tip at 0:50. You use your right hand to do a B flat and D chord to complement the melody line. This is good in practice, but here you lose efficiency in your playing and make the melody seem chopped because you are jumping back and forth. I would recommend using your left hand in this case: what you can do is play with the 5th finger G, then second finger D and first finger B flat (that is, G to do the bass, followed by D and B flat in chords, which is G minor chord). That is a big stretch (10th), but it will add a lot of substance to your playing, and will cover all the notes you don't use between the right hand and the left hand.
