First video -
wtf @ ~ 00:38. Why did you fall all that way and nearly die? 0_o
00:52 - Shiri style egg lay to taunt. First, if he went between the platforms or even landed on the left one he could've easily d-aired you. Second, you could've done a normal grab and then combo'd into something. I know you had fun with this move, and it is a friendly, but take your chances when you can get them! ^_^
Straight after the taunt - Spamming b-air is good, and because your opponent fell for it then it worked. However, all it would take would be 1 CC and he's kneed you in the face.
2:06 - Yeah, the down B. After you realised he missed, you should've done a b-air and fast falled instead of down Bing. I'm sure you know that now though ^_^
2:46 - No DJC up-air combos? The only reason the f-air hit was because your opponent didn't tech or try to jump out or DI. Still, it was effective, so if you're facing that or a similar Falcon again go for gold!
3:18 - You were too far away to hit with that up-B. At best you should have aerialed out of shield or something. ^_^
1st Video general impressions - You like your grounded jab game a lot 0_o. Some opponents can handle it and some can't, and you got lucky in this one I think. Obviously you don't DJC often, unless that was a little technical error in the middle where you got kneed in the face after a DJC on the spot. Otherwise, your Yoshi is definitely good and as all good Yoshis need to be, its fun to watch.

2nd video
00:13 - I would've d-tilted out of shield here. The attempted DJC wasn't going to work if he jabbed or f-tilted or dash attack etc so d-tilt was definitely the better option. I know, you were probably scared of the d-smash, but yeah.
1:04 - omfg you actually got the first stock off. I didn't expect that. Good job!
1:11 - lol.
1:18 - F-tilt!!! Tapping won't combo! >_<
1:33 - Ouch, unlucky. Did you DI upwards then? If so, then ignore this comment.
1:40 - Sidestep!! Shield the first few hits, and sidestep into d-smash. Sexiness.
1:45 - The f-tilt wasn't that good an idea here I think. I would've used d-smash, cos you'd get Peach off the edge, and Yoshi is very good at jibbing Peach's recovery. Eggs take out float, instant edgehog stops her superpriority etc. Keep that in your mindset, a Peach off the edge is worth 2 that have been f-tilted.
2:00 - Wth? Oh well, at least you both died!
2:06 - I would've used eggs instead of jumping into a b-air. Approaching the upper platform is dangerous when you can't reach from the ground with your first jump, because its harder to fake out the d-smash.
2:11 - I would've f-tilted, only because it would be more likely to break her CC and prevent any CC'd dtilt or dsmashes.
General impressions of the 2nd match - Lightshield more, like technomancer said. You were getting shield pressured a lot, and a lightshield into edge eggs is sexy. Otherwise, I really can't help you, as it is definitely hard to approach a good Peach, and that's where you had most of your problems. *Next one downloading*
3rd video -
That Ness is kinda weird. The only reason that strategy worked, as far as I can tell, is because Yoshi has no real priority forward facing moves in mid-air that are quick. But really, I can't see it being as annoying as standard SH f-airs, except that these DJC'd ones are difficult to punish unless he's spamming it more than he's paying attention to your adaptations.
Still, when you f-tilted his f-air approach it seemed to stop him in his tracks. That wouldn't work with standard SH'd ones >_>.
*Found Nessby more impressive*
Anyway, rewatching.
Ok... I don't think I'd change much of how you played. He didn't get close enough for you to take the PK thunder and stop his recovery, but he did stay far enough away to get instant edgehogged easily. Watch for that more next time. Other than that, I reckon I would've done just the same against that Ness.
Btw, awesome Yoshi Shiri. I likes it a lot.
