Yes, consistency is key!
The ones in the QR Corner, the images I use for it, are specifically "Pokedex Images" extracted from Pokemon Sun and Moon.
(the ones you see when you scroll your Pokedex)
However once again, as the games are unreleased,
we don't have that image for this Pikachu,
so I'll probably change over the images once the game is released.
edit:
I merged the images between Original Cap and I Choose you Cap (as seen on the Ga-ole),
but I may not use it and instead wait for the official image.
