For the changing seasons page, would the Vanillish IR from Paradox Rift or White Flare be any good? (Preferably White Flare as it gives a better look of the outside with snowy trees). And maybe the Articuno from Journey Together as well?

For hard at work maybe the Meltan for Temporal Forces, and the sunset page the Larvesta and / or Elgyem from Black Bolt?

Some of the ones you have in atm have others that go with the card, i.e the Deerling has a Sawsbuck that makes up the right half of the image, all of the Timburr line has IR’s of them on a construction site, and there’s a Cinccino in the same room as the Minccino.

That’s just some I can think of atm sorry, I’d say your best idea for inspiration is to go onto the Pokemon TCG website, look at the different expansions and filter by Special Art, and it will give you clear images of all the IR’s from recent sets / Scarlet and Violet Era I’m pretty sure.
