First match:
Your improvements are quit noticable.
As I can see, there were lovely uair to upsmash combos (you love them now, right?), and better selection of moves.
The more practice is required, as I saw quite a few mistiming and or mis-"spacing" errors from your fairs.
Also there was too much fsmash usage, you used it as a shieldhit punisher, which was good, but don't rely on it too much. Especially if you've already used it several times recently, you were better off using a dolphin slash or DSMASH (which would have killed a little earlier at some points).
Some points seemed a little off still though, and of course I still criticise the speed you move at (though it has sped up a bit, which is nice).
Like after the 3rd stock you suddenly stopped moving from time to time or something, which I know it wasn't wifi, but made me feel as if it was.
Sorry I didn't do a second to second thing, as I wasn't going to record this one this time unless you wanted me to.
Second Match
Fthrow at 0 percent gives you a guaranteed tipper fsmash.
You did some silly fsmashes here as well.
Over all:
Start fast falling your aerials a bit and work on following up said fast fall'd aerials with more hits. Fast falling can be a lot better if your opponent shields one as to give you more speed to avoid punishment.
Much better move choices, but at some points I felt you could have used dsmash and others even use utilt.
You should now put some effort into the things above plus working on some of your grab game.
Also do watch out about the usage of Forward Smash and Shield Breaker.
