You have to work on your technical consistency and your predictability, here I'll give you a quick analysis of what I found wrong in the second match since the first match was a bit shaky on the camera =0.
0:11 - Easily readable approach to attack on platform, if possible when they're at that situation try to waveland on the platform and do something or fastfall, don't be caught in the air, also, when try to stay off the platforms as much as possible, don't linger
0:20 - Wak read your jab well, although there isn't much you could have done I advise you to space yourself out more and always use lasers in your approach before responding with moves
0:25 - Messed up LHDL...work on technical consistency
0:37 - Messed up fastfall from Dair...work on technical consistency
0:59 - Again he caught you out fo the jab, unless you're 100% positive you're going to hit try to respond with aerials or space with lasers
1:06 - Technical Error, go for the edge ^^
1:10+ - Now that's what you should be doing Laser to Aerial approach... don't try to catch people with jabs =P
1:14 - Either edgehog or lightshield edgeguard, don't wati for them to come up and than try to hit them.
1:28 - Technical Error, fast fall the Nairs
2:28 - Don't be so eager, go out and play defensive =P
Normally when I watch people's videos I usually am able to make generalizations about what they got wrong, for you it was a bunch of random things so I kinda had to go play by play, which is a good thing because it means you just need to work on consistency, anyways keep it up, you have a good falco ^^.
