The only really damning ones i see are the duplicate face and the three fingers, and i actually think both are not signs of AI. With the 3 fingers, it looks like his index finger might be perched on the other side of the flagpole out of view, like some people hold a pencil. With the duplicate face, that seems much more like a human error. A graphic artist filling in the background got lazy. The whole thing does have a kind of fultered overproduced look that reminds me of some AI stuff, but I don’t see anything conclusive, and a lot of the examples pointed out below are definitely baseless.
