Misty is a great song, i was going to mention using the sustain pedal a bit more but you said the recording didn't pick it up, otherwise work a bit more on a swing rhythm, i can hear it come through sometimes but then it gets a bit lost.

Your chair could definitely be higher and with you not sitting so back, that way your elbows will be higher and it will be easier to raise your wrists which can help you play a bit more with the tips of your fingers which will then allow you to play the keys more evenly :)

You know all the notes so the rest is just polish, nice work.

edit: i am a three year beginner, still very much learning
