I looked up the photographer and he said this in a post on fb:

Evening ALL
I’m almost certain that some of you will remember my BBC Countryfile Calendar winning image in 2017 of the water vole picking berries by a riverbank.
Well, as you know I now dabble with Al and have conjured up this piece of work in watercolour with the main elements from that original photographic image…
Hope Ya Like It and thanks for looking

Surprised a photographer would even think about using AI like this, not good.
