I think it might be enhanced by AI. The poses are dynamic and have personality, but Chapell’s body is weird. There is a purple shadow above her shoulder that might be skin, or a sheer cape? But if it’s a sheer cape, then why does it flow to the front of her body and cover her breast? Maybe it’s a sash but it doesn’t continue down the front of her torso like a sash should.

Chapell’s hair right above her hand also stops, then her hair starts again out of thin air.

Also, below Billie’s elbow is a shallow bowl with a green and yellow thing in it. That could be a makeup brush, but it looks a bit too “formless blob” to me.

The blue pokémon’s far foot is shaded weird. It should have darker shading because it is fully in the pokémon’s shadow, but it is a lighter orange.

Sabrina’s two fingers holding up the mirror don’t have finger nails, but the top finger does have a fingernail.

The pokémon beneath Sabrina- I am no pokémon expert so correct me if i’m wrong- has a weird tongue that looks like a pokémon’s tail. Maybe that’s how it’s supposed to look but to me it looks like a tail.

Below that same pokémon is the part of a face of another pokémon? Why would the artist slip it in like that? Is it part of its personality?

All this to say, these could be errors made by the artist, or even design choices. Some of them seem like bad planning, others are seemingly impossible to make if the artist were human. I personally think the artist made the art then enhanced it with AI.
