You're just... really obvious. And you're not punishing stuff that well, and not catching on to what he wants.
Your ledge pressure is terrible, your Dsmashes are weird (like I saw you Dsmash at low percents, but your gimp game is bad, so you're putting them off stage, giving them a free ticket back on stage, and staling Dsmash. Since you SL so much, Dsmash is like your only legit kill option (that and nair, but I didn't see much of that)) and you're just lucky that the Falco wasn't punishing them as much, your shuttle loops are pretty obvious, but you hit with it so much, and your gimp game is so bad, that you're not getting kills until lateish percents, your uairs are badly spaced (I wasn't paying a lot of attention, but I don't think you hit with a single uair while sharking lol), your nados are kind of unsafe, your glide attacks are extremely obvious, and you're just missing punishes, being unsafe in general. And bad stage control, but stage control vs Falco is a bit complicated, so I'd work on the other stuff first (although stage control and ledge pressure go hand in hand).
And STOP DASHING SO MUCH. There's a thing called walking where you retain all of your options. Do it more. And I think I saw more Dsmashes than tilts... >_>
It isn't Falco specific stuff other than not catching on to when he wants the grab. I mean he's being really obvious about going for the grab when you're at 0 every time, and every time (atleast from the second match, didn't watch the first) he'd get it really easily. Other than that, just... work on the basics lol.
idk this IS based on one match, and I only watched it fully once, and then scanned through it a bit a second time, so some of it might be off, but those are my first impressions.
