Really not bad if you're only just getting into ukebashing.
The first thing I would say is you're not going to get the movement you need to make a cool replay by holding everything, try and relax more stuff.
I would also say that you should be more decisive in your movements. In 'Spaghetti & Pasta' (great name), you went to contract your knee but exended it and then contracted it again before you pushed off the ground with it. If you do something too early, just edit it before you do it and try again, it'll make your replays so much better, trust me.
Great start though
