Ok I am back.
Your game play with Pit seems to be really lacking. your approach was non effective, arrows weren't used to full extent (if used at all). Not too much tilts or grabs. But it you can improve.
What to improve on.
---------
Fundamentals; Spacing; Approach; Mindgames; Knowledge of your character
---------
Fundamentals
It seems as thou you have not fully learned the fundamentals of the game yet. It didn't seem like you knew what you were doing out their. You were kinda just walking and f smashing. And you rolled alot. So for this I suggest you go read up on our Pit guide written by the Kupo and CF.
The guide is found here

Besides reading that guide play around with the game mechanics a bit and go read up on the mechanics in the main boards (I am sure their is a thread somewhere I am just too lazy to go look for it XD)
---------
Approach
Your approach with Pit was lacking, lacking too much. The only approach I saw was Full hop Dair or a dash attack. I didn't count a single SH Nair. Approach with that instead. SH Nair into their shield and they will get hit, then you can follow with a combo. You can also use your arrows to as an Approach. SH arrow while moving forward, using the arrow's hitstun as a reliable wall for you to approach from.
---------
Mindgames
You don't have to know the advanced techs to be good at mindgames, (
I suggest you don't even learn any techs yet until you have established a better ground for your game) Simple jab fakes would be great. Try to go jab > jab > grab ; jab > d tilt; jab > jab > f smash. You can really mix it up and make it your own style these are just combos that I use.
---------
Spacing
This really goes back to learning the fundamentals of the game it self. After learning your character more and the fundamentals of the game, Spacing will just come natureally to you.
---------
Knowledge of your character
It seems as if thou you haven't learned your character yet. Your just kinda wingin (lol wings) it and hoping it works. Reading that pit guide would help you solve this problem.
Well I am done, I hope you take my advice and become a better Pit player Now i am off to eat because cross country is a b*****.
P.S. I just realized that your friend is the pit not you the OP. So every time i say "you" pretend i am talking to your friend. Have fun.
