@Greyfox, nice use of the ftilt combos
4 things I would like to point out
1. use more n-air, it is a great aerial and makes a great oos option, especially since our "normal" grab range is quite small
2. use less f-smash, it can be very tempting to use but will rarely work and can be severly punished, it range might seem attractive but there is always a better option than f-smash
3. u might already know this but judging from the vid, just to let u know that sheik has more than 4 directions she can vanish, even more than 8, so if your opponent is edge guarding you , aim to vanish in an upwards diagonal.
4.u almost took advantage of this, at 1:11, instead of going for the flurry you could have changed your direction of the f-tilt and still got it to combo, useful tool for characters that find it hard to escape or opponents who are being lazy with their SDI
but all in all, a good performance
