I think you're being too hard on yourself. Your performance was actually very good (and of course it's always harder when that little red light is on!!).
If I may offer one minor constructive criticism it's that you're not holding the dotted crotchets for their full value. I'm referring to the notes in bars 8, 16 & 48. The dot next to these crotchets (1/4 notes) means that they are held for 1 and half time their length (i.e. 3 beats in this instance given that the piece is in 3/8). An easy way to check this for yourself is to count 1,2,3 for all the bars as you listen to the piece. You will notice that when you come to these bars the 3rd beat "disappears". I hope this makes sense? There was a similar issue in Bar 32 (I think you forgot to play the B on the 3rd beat of this bar?).
But other than this small issue which I'm sure you can easily resolve, overall I really enjoyed your performance.
