Some of the lines on the wings look a bit weird for something a human would do but yeah it’s hard to tell. Course any good AI art these days has some amount of manual editing on top of it to clean up any artifacts so if they’re doing that it can make it less obvious.

Also if you crank up the contrast a lot you can see there’s a bit of noise in the otherwise clean background, given this is a PNG there shouldn’t be jpeg artifacts or anything like that which is probably the biggest indicator (since a human artist would generally have a perfectly clean background, but AI struggles to get it exactly perfect). It does have some jpeg-esque artifacts though around the character so who knows though, maybe it was a jpeg originally and re-encoded, but I wouldn’t be surprised the AI just learned to generate those sorts of artifacts itself or something by being trained on a bunch of jpegs.

Is…this really AI?

This doesn’t look like AI in the slightest. It looks like someone drew this.

That makes me very concerned if it is AI, though…
