A small suggestion. When you have your opponent in the air and stunned (like after one of your dairs) rather than dair them back into the ground try to go for sweet spotted bairs. If you feel you can't get off a sweet spotted bair go for a nair.
I think this would put you in a better position. Sweet spot bairs have really nice knock back, nairs are pretty good as well. Even if you're not trying to kill them it can knock them off the level and you can edge guard them (rather than keep them on the level).
The thing about giving advice like that is that it doesn't apply to every situation. While that DOES work in many situations, some options would be better.
Like I can argue with you and say that at low percentages getting the opponent in a fair/uair chain would be better. Or at mid percent perhaps you can pull off a weak bair to sweet spot bair combo, etc etc.
It may help a bit to give suggestions that are that specific, but sometimes it's better to be more general.
Like, how 7ill should work on his spacing and perhaps take different approaches to his arial game. Also, as far as edgeguarding goes, you seem to just let him return to the edge. Now this is actually the ideal approach to take at times, but not in the situations you did it.
Sometimes the point of edgeguarding is not to actually hit the opponent away, but to add pressure to the returning opponent and to limit his options so that you can act accordingly.
Example: Shooting missles, throwing ftilts out, shooting a charge shot.
While these options may not always hit, the fact that a charge shot/ftilt/missle is coming his way actually limits his recovery options. A charge shot, even if missed, limits the opponent to only being able to return from above the shot, or in some cases below. Either way, you cut his options by 50%, and it makes the job easier for you.
