Hmm.
1) Here's one thing that caught my attention - you barely/rarely DjCed.
That's not specifically a bad thing, since it helped you stay alive (since you werent getting hit out of your DJ)
But instead of resorting to short hops, you did ALOT of fullhops.
Infact, both of you guys did alot of full hopping (i cant help but watch the doc more since ima doc main D: )
So i'd suggest you either work some short hopping attacks or DjC'd attacks into your game, to quicken up your game.
2) You're not a big fan of punishing. (or not in this video, atleast)
Like i said, your friend did alot of big, full jumped attacks (and alot of sliding attacks. PLEASE TELL HIM TO STOP DOING THAT SO MUCH. D: )
Because you dont do alot of shorthops or DjCs, i thought you were kinda scared punish him. (Which I would be too).
You do have safe, quick options to punish him for missing techs and taking too much time. N.air and f.tilts are the main ones.

Everything else looked fine to me.
Had some good control of PKT2 (except for the PKFailure, but that happens to everyone :/)
Good overall movement and spacing.
Just keep up the work.
