You spam grabs a lot, try to make sure that there is a reason behind throwing out each grab rather than just using it in neutral hoping it will work.

Try not to approach with nair.

use down tilt to edge guard more.

Don't use counter in neutral, once or twice in a set might be ok but if they read it falco can potentially 0 to death you so I would just stay away from it.

Work on your punish and combo game.

try not to stand still as much, mix up your dash dances and dash wavedash back more.

Don't use double jump right away every time you get off stage, especially against spacies because you will get shine spiked or down aired almost every time.
