Your movement is pretty choppy. Not sure if it is lag from Netplay but that doesn't seem the case for the Yoshi. Mainly in the first match after you did an attack, you would not move or just walk slowly when the Yoshi is flying around. Just practice simple movement on most or all stages to be more comfortable moving around and how you would move when the opponent is doing something. I noticed that your main ledge option was to immediately jump then D-air which was always punished, so you need to have more mixups on that, as well as your recovery.
Your DI isn't too great, in the first game at (1:20) I think you tried to DI down towards the stage and tech but messed up the timing and air dodged to your death instead. You are good at waveshines and L-canceling but you seem to mess up wavelands and wavedashes a number of times which isn't too important but are still handy as a Falco player I assume. Another thing that was obvious is that you seem to have trouble following up. Sometimes you would land a shine and jump but then you would throw some aerial like F-air and not be able to do anything afterwards.
On a stream from Westballz, he talked about the reason he doesn't laser too much is because Falco gets punished hard for laser camping. When he does laser, he is eithet stuffing far away approaches and recovrries. Other than that, he mainly uses shine, things like D-air and B-air with overwhelming pressure and edge guarding tactics. You on the other hand seem to laser just for the sake of damage. Practice your laser-game and approach options, you seemed to mainly use D-air and F-air to approach or try to stuff the Yoshi's approach which wasn't very handy.
Pretty much, your movement is not fluent and you miss opportunities that are golden for a Falco player. Not great at approaching or stuffing approaches but you are good at getting out of pressure but you let the Yoshi do whatever he wants.
