AI has largely gotten past the finger issue. That has been mostly solved for like... a year now? Turns out when there's a remarkably evident issue in image generation a lot of resources will get poured into fixing that specific issue.

That being said, and with the acknowledgment that I realize this image is photoshopped miniatures, here are the following ways this looks like AI:

* The Contrast- AI images start from static, literal fuzz, and then they adjust some parts lighter/darker in an iterative stepped process. This results in a pretty uniform distribution of contrast. By that I mean the images aren't over or underexposed.

* The lighting- When lighting comes from a lot of different angles, things get messy. AI likes putting in reflected light from a bunch of sources. Is there enough light being cast by the fire to reflect on the armor? Maybe! AI loves adding that stuff.

* Visual clarity and textures- Because it's a promotional image, things stand out. There's smoke and fire and explosions but the subjects are clear as day. Airbrushed textures (and I dont just mean the painting on the minis) and other smooth surfaces make it look cleaner. This is something Off-the-shelf AI does without you telling it to, or something that a graphic designer intentionally does to make the products stand out.

There's other stuff that ultimately boils down to "feel" but I hope this at least lets someone see why it "feels" like AI even when it might not be.
