I watched all three matches. I'm not yet what I would consider "good" (even at the local level) but I can offer advice I think would be beneficial.
First I'll say what you did well:
You seem to have a decent grasp of the basic AT's that are essential to playing well, this is a good foundation to build on.
your dash danceing was very pretty, and you flowed well throughout all the matches (although with people that will not be as easy)
Improvements:
Really try to find real people to play, fighting cpu's is getting you into bad habits.
The knee is not a good approach. It's a good punisher, and nice to combo into, but a human will not let you run up and knee them.
Same thing with raptor boost, you can get it occasionally or as a tech chase, but real opponents will easily avoid it and punish.
I noticed you used the get up attack to get off the ledge most times. I wouldn't recommend this so much. If you are edgehogging , roll off edge is better. To attack an opponent off the edge, try ledgehoping a nair or uair, or if you are feeling lucky, even a knee.
Off-stage edguarding is very flashy, but against people is VERY risky, especially against certain characters.
Did you notice how ganon always DI'd back from the raptor boost, people mix up their DI, so forwardb>knee isn't always that automatic, you need to read their DI.
Overall, I think you've got the basics down well, find some real people to play and it shouldn't be much of a struggle to fix any potential problems I saw. Other people will be able to tell you more.
(note: If you [the reader] disagree with anything I said, say so, and I'm probably wrong. You can then effectively help two people (cf741 and myself) )
