That artist also forgot reins. And the front wheels of the carriage are goofy. And the city is a bunch of squiggles. And there's a bizarre oversaturated smear of farmland in the distance. It's the sort of human drawing that makes people go 'did AI draw this?' because a year ago they would've just said 'this kinda sucks.'
The psychedelic waterfall one has the opposite problem, where the tree at left immediately had me go 'that's a robot,' but it is also how humans draw when they've done quite a lot of drugs. Anywhere besides a landscape it would be inexcusable. But there's every reason you might want to draw a tree, that way. An anime character eating ramen - not so much.
