oh hell yeah.
<3 your use of u-air, i def took notes, it's such an underrated move. ****.
against sheik in the first match, your first death sheik d-throw to up-smashes you. i THINK you could up-b out of it before she can u-smash you there, because it took her a while to get that off. Not that that's a huge deal anyways because she coulda just u-aired and got the same result, but just saying.
not a huge fan of sidestepping vs. sheik (or in general with g&w, although it does have it's moments!) she can punish it too easily.
your edge cancelled aerials are ****. fooled sheik so many times with it in the first match, very nice.
good edgeguards against sheik, intercepting her up-b with f-air and n-air twice, aggressive edgeguarding vs sheik ftw, i agree with that
when your shield eats up a sheik d-smash, wd out of shield to grab all day! that one time you just rolled instead and then got dash attacked! i'm sure u know that though anyways.
also on dl when you're recovering, the sweetspot area is really huge, which means you can up-b from a lot lower. shouldn't get d-smashed by shiek while recovering! though you probably already know that too (: lol

your gw on brinstar is a monster. all those edge cancels and mindgames...too good
one habit you might have that i noticed (because i have the same one) is that when you're trying to Maybe finish off a combo, like on brinstar at 3:48, you get a nice combo, f-air d-tilt n-air, then you go for a tech chase f-air, which you clearly know sheik is gonna get her shield up in time but you went for it anyway! when you know that happens, even though you know you COULDA gotten it, you gotta back off and reset it, cuz you know you'll get punished for a non-spaced f-air like that, not worth risking it. i have the same habit of "going for it anyway".
as for match 3, and in general for these matches, if there's one thing i can point out about this matchup in general for you, it would probably be that i think you should jab more. it's really the only move that's faster than sheik's tilts, and can outprioritize them and lead into other moves. I saw you were able to jab grab fairly often, like on brinstar, which is good! but definitely used them more if sheik is going to play as aggressive as she did in game 3 on bf. gw's jab is soooo good.
EDIT: also on battlefield, you have to stay clear of sheik throwing needles from the platforms by all means. once you get hit with a aerial needle, she can fall on you off the platform and f-air, and there's nothing you can do at all (other than shield) because there's too much stun for you to get a u-tilt or u-air off in time. and after the f-air you get grabbed, and once you get grabbed, life is no fun ): so really watch out for those needles especially on the edge of the platforms on bf....they're so nicely placed for sheik
sheik's approach really is not that good compared to some chars like fox, so really letting her approach and using jab and cc d-tilt is a fairly good strategy. but you had nice baits and good reads overall.
not gonna look over this post just yet hope it makes sense and it helps!
