They're leaked, and thus unconfirmed, so they shouldn't be sourced for articles.

However, it's fine to discuss them here until there's an official confirmation.

Personally, I'm extremely confident that they're legit. The style and quality match the other settei from the movie (and from pierrot productions in general). Some of them even include the same settei that are on the official website, in higher quality, along with matching turn-arounds and facial expression references. The creatures and characters can be spotted in the trailer, and many of them are so practical, detailed, and innocuous that it seems pointless to question their veracity.

The crab monster and vulture summons, for example. Why would somebody fake production sketches of a monster that was barely glimpsed in a trailer just released to the public a few days ago? And if those model sheets got leaked, what's to stop others from being leaked?
