A few tells:

No left arm: <https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....>

Possibly nonsensical shirt text: <https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....>

Bottle labels a little ... too ... vague? <https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....>

Utensils on plate seem off: <https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....>

"ARXTC" text (on building) seems nonsensical: <https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....>

Most obviously: man to far left has unnatural left hand, text throughout image is nonsensical (box, bottles, signage, fridge), faces and hands of men in black t-shirts facing camera are both mangled, food on foreground plate looks odd, and what's with the table piled in white powder (cocaine? flour? laundry detergent?): <https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd....>

Save for the last most of that's nit-picking, and on casual glance I'd miss most of these.

There are many small errors in some details if you look hard enough in images with many objects. But on the first look, these look like casual random photos. They simply don't stand out like your usual generated imagery.

I can't spot anything out of ordinary in the second image (man with green sweater) for example.
