I don't really know how to critique these. I feel like I'm being arrogant with my thoughts here but I'm going to be honest.
There wasn't a whole lot here. You both played pretty predictably, after your 2nd falling Overb I was able to successfully predict every other time you were going to do one on the stage. You both seem to play very single minded. You seem to have fine techskill, followed up your shffls well with grabs and dashes. But there didn't seem to be enough variation for me to really judge. Pretty sure these are friendlies, but even so I just don't see any real feints or counter strategies in these matches that worked.
Other than techchasing (one of the minimal uses of dashdancing) dash dancing was barely used properly. It's hard to judge videos when the only counter approach seemed to be the Fox's double jump approaches. Maybe today was not a good day for me, but that Fox did some horrible approaches. I feel like 90% of those nairs he approached with could of been CC grabbed (CC pushes you away from shine most of the time).
I think the way I would describe this playstyle is 1st choice. Almost everything you guys did seemed to be your first choice. Your Fox friend always approached with nair, never varied his distance with dash dances before nairing, always tried to attack the tech chase rather than trying to see if you had any spotdodge or roll pattern. Neither of you walked, dash to shield (a major for Fox imo). Just seemed a majority of the time was a lot of blind swinging around for approaches. You would occasionally try to camp, but it never actually ended up being camping at all it seemed. When you were both next to each other, both of you thought attack.
I don't really know what else to say. Other than you both seemed to play the same for the entire match, and since neither of you countered what the other was doing it just went back and forth like that for the whole duration.
