>>57106670NTA, but from the top left to right: Catches Pancham, Master Class, Serena and Bonnie man the PC while Ash repairs the roof and Chespin and Bunnelby go shopping.
From middle left to right: Serena after Ash comes back from the blizzard, Serena after beating her mom in the Skiddo race (top), Serena winking after getting invited to join Ash's journey (bottom), desu could be either of the showcases she wore that dress (top), Couriway showcase (bottom), the Pokévision episode's baking scene
From the bottom left to right: Serena in the first Rhyhorn episode after the flashback where Ash remembers she was the "girl with the straw hat," I'm stumped because this could be any Serena frame desu, Serena after Ash agrees that her new outfit and haircut are cute, and finally the TBC shot after the Master Class ends.
Those are my guesses.
