Personally, I think you shine way to much. It's a good move but shouldn't be used as much as your laser. Also avoid using laser while grounded. It has a ton of lag. And work on the timing of your SHL and SHDL so the lasers end up closer to the ground and don't just sail over your opponent
Try to keep Fsmash fresh for when your actually going for the kill. I don't think I saw any tilts being used. Ftilt is a quick move with a nice sized hitbox.
Instead of your jump off phantasm (<B) learn Instant Ariel Phantasm (I forget the name >_>). You just run off and imediately phantasm. Fast and lagless. Also, avoid using Firebird. If you were facing a human you would most likely get edge gaurded.
Not much advice I can give since your facing a CPU
