Very nice I didn't see a single missed L-cancel, incredible
I counted over ten.
@Op: You need to grab more (from grabs you can combo characters, tech chasing works really well, it also allows you to control the flow of the fight better), work on your spacing (as in, controlling the distance between you and your opponent so the tips of your attacks will hit him, this helps because Ganon can out range most characters), and you really need to work on DI (DI is controlling the direction your character flies in, this helps you escape combos and edge guarding tactics).
You also need to work on reading your opponent. It seemed throughout both sets that you were just spamming random aerials, hoping something would connect.
And lastly, work a lot more on getting closer to "sweet spotting" the ledge with his up-b. You were really far up over the edge against Falco, I didn't pay much attention to it during the doc matches. The closer you are to "sweet spotting" the edge with ganon, the more likely it is you'll be able to ledge tech when they try to edgeguard you with a dair, d-smash, or f-smash (any attack that will hit you really).
Hope this helps, and remember, keep your eyes on your opponent's character, not your own.
