I'm no professional but..just helping :D
I personally don't think you play aggressive enough, a quick example would be in match two at the beggining, you sat in the back and laser'd. I personally would run at them or go back and forth while lasering that ganon, keeping him stuck, and once a good opening comes up, go for it. not saying don't shield at all obviously, but you need to try and be on the offensive side alot more than ganon.
Learn to do **** OOS. The ganon was fairing your shield alot, and usually you didn't do much about it.
Your ledgegame needs to be changed up a bit. I noticed he punished your ledge-hop dair with a fair, you survived, and ledge-hop dair'd again. Falco has a **** ton of ways to get back on stage, you could firebird stall, forward b to the middle of the stage, or just the generic hitting L, R, X, or simply forward. Your goal at that point is to get on the stage and sruvive, not to start a combo up :D
I dunno if you're doing it on purpose, but I would stop D-smashing your opponent at such low percents, usually they can hit you again before you can hit them after even connecting a d-smash.
Don't laser so close D:
Mixup your approach game. More nairs and MUCH more grabs. [Shine -> dair -> shine -> repeat] is extremely expected from any falco, so most decent players know how to react to that. Your chances of winning this match would have been MUCH greater if you grabbed him, because all he had to do was sheild your approaches -> ****. This is probably something you want to work on the most.
And uhh, i don't suggest using your second jump into an offensive move, one hit after using your jumps with falco usually leads to death X_X
Goodluck =)
sorry i wrote so much x_x
