I know this critique is like a whole week late. But I'm going through alot and I've barely even been on smashboards lately. Anyways, I got enough to critique one of the vids for now. I'll try to get to the rest later.
@0:43 After you landed the f-smash, you opted to throw pills from center stage to edgeguard Falco. Pills are actually good for covering the Falco's illusion recovery. But you probably should've rushed towards the edge of the stage so that the pills could have a better chance at disrupting Falco's recovery.
@1:47 Good grab. d-throw -> d-smash is pretty much gauranteed at that percent though. You tried d-throw-> f-smash which doesn't work until a bit later.
@4:38 You got a grab on Falco on FD when he only had 35%. Forget about d-throwing, it was time for you to chaingrab him.
@5:55 Again, you got a grab at Falco on FD. And he had no damage at all. CHAINGRAB HIM Although you were probably close enough to the edge to where you could've gimped Falco. But edgeguarding Falco at that percent is a coin flip, and sometimes it's better to chaingrab to get the gauranteed punish out of the grab you land.
There were quite a few times when you got punished by Falco's shine approach, like the d-air shine @ 2:09, and the b-air shine @ 5:07. Sometimes you gotta wait until after the shine to try punishing Falco.
Other times, you were kinda above Falco too often when it wasn't working out in you favor. Doc's slow falling speed is too easily punished by Falco's up-tilts and b-airs. And being in the air gives Falco a free approach since Doc can't really defend himself with anything to keep Falco from approaching freely with a d-air (other than to maybe switch up the falling styles with wavelands and shields.
I would suggest being more mobile on the ground vs Falco. Doc controls the horizontal space much better than the air. Mix up those out of shield options whenever Falco gets in on your shield. You gotta predict/react on times where it's safer to attack out of shield, or when to jump out, or when to just simply roll. Since you'll probably need the shield alot too, I would suggest utilizing the lightshield as well, just to make that Falco player have to press more buttons and work harder at landing hits.
