Nah, I'd be more than happy to. Cause watching other peoples videos gives me ideas how to improve my game too.
**RESERVED FOR VILLI's EVENTUAL CRITIQUE** hehe
Ok, after watching the diddy vids, I'd say you did about all you could do vs. the banannas, keep the fight close to him and pressure his shield with ftilts and the like... I'd like to see a little more ftilting, and possibly a little more needle usage, but you did well. And although I know nothing about Zelda, you have a good one. One thing I might suggest is that you keep on glide tossing, but once you glide toss, do like a Dsmash or Usmash afterwards. When I fight Diddys with my Meta Knight, I glide toss often and find that I can KO easily this way. (Glide toss->Dsmash/Fsmash)
Overall in the diddy matches, I was pleased that you used his bananas against him, a lot of people don't do that, and slip until they die.
AND I LOVE THE JAB COMBOS. They are good. And especially good when they are used near the ledge and your opponent wants to DI twoards the stage rather than away, thus taking more damage.
(Specifics)
Vid 1 vs Diddy
-Where is the Dsmash? I never saw it. I often use this to punish spotdodging, and it's a quick punisher. Especially since you like to Down+B for the kill, I suggest abusing Dsmash for damage (it can do as much as 20+!)
-Good OoS Nairs for quick punishment and comboing. Good Fair momentum cancelling (DI or whatever)
Vid 2 vs Diddy
-I know Yoshi's Island is small, but watch proximity to your opponent when using your needles, I saw more than one occasion where you got punished for using needles too close to your opponent.
-SEXY ledge drop Lightning Kick.
Yay more Dsmash!! (Isn't it great?) More needles too, but in wrong places quite often. But it is hard to use needles against that Nannerz guy cause he likes to be up in your face pressuring you with bananas. Likewise you pressured him quite well.
Good job overall despite losing twice hehe. But Diddy Kong is an extremely difficult matchup, as is an extremely WEIRD matchup, which requires Sheiks to kind of not play how they normally would be able, with bannanas being in the mix.
