I swear, I did not use any AI tools

I just wanted to have some fun. AI tools can really unleash creativity. The image is mine, I took it yesterday with my Sony Alpha 7II. The lake is the "Upper lake" of" Laghi di Fusine" - Italy, Tarvisio. The giant duck is fake.... maybe... The buyer can contact me and request the high-resolution original picture (+, if desired, all the others taken that day).
