So, can anyone tell me anything I'm doing wrong? I know I can still improve.
Honestly, it was very hard to critique your matches because your opponents did make some rather questionable decisions. I can recognize that your fundamentals are overall solid, mostly. But maybe I'll revisit your matches and come back to edit this post once I get a slightly more confident feel about where I think your in-game decisions come from.
Okay, critique time:
The B-airs
here were not well thought out. That was a risky decision on your part, as a result of misjudged spacing. You realistically should not have committed to the second B-air while you were landing even if the Yoshi was in range for it, given if he was proactive about it, he could have read and powershielded this fairly easily. The only situation in which the B-air might have won you something is if he committed to DA at the wrong moment.
While I feel you have a good handle on F-smash reads, they're not always the best idea against tether grab characters. Consider
this moment. Honestly, this is more a matchup specific thing than anything, but here you probably should have considered Jabbing. Yes, it's still good against Yoshi precisely because of his poor grab.
You actually should be using more fireballs, just generally speaking. Especially grounded fireballs. Yoshi does not have a clear punish for them unless he basically does Egg Toss right before you Fireball. Fireballs are something you should use not just simply to harass, but consider doing them to cover his landing options especially as he moves around platforms.
This was likely an opportunity to Jab cancel combo into Grab/D-smash that you missed even though his invincibility wore off. I know in the heat of the moment you want to roll away from spawn invincibility, but realistically, Jab was a safe punish option here, as his invinciblity was gone before he landed.
I think overall from what I've seen about how you play against Yoshi, you need to be more confident in spacing fireballs and using them to cover options. You got punished a bunch of times for short hopping while not facing backwards. A lot more of your success came from when you stuck to good grounded fundamentals, saving your aerials for punish situations and capitalizing with Smashes and grabs in good situations. There did appear to be slight inexperience against Yoshi because moves like Jab were underused, and some of your aggressive aerial spacing is not always wise in this matchup except in situations where you have Yoshi committed to footsies (B-airs are great against him if he tries to just play footsies, because you'll blow through his aerials favorably and you can sorta directly wall out most of his grounded attacks unless he spaces U-smash really well). Though as you've stated yourself, you know that you are overall stronger than this player.
Might be back with a bit more later...
