This was stuck in the ground at the side of a freshly resurfaced road in Hemmant where I parked this morning.
It probably is AI, DiaDeLosMuertos is a very well known Prompt Artist who frequently posts his works on this sub-lamington.
Honestly, his Prompt Art is better than a lot of biological "artists". It really makes you wonder how much life is left in traditional art now that Prompt Artists are becoming so good at coming up with such amazing works.
