Arafed man riding on a turtle in a western town

absurdist oil painting of a ruggedly handsome cowboy, age 50) riding a (giant turtle with a green shell, and the turtle casts the shadow of a resplendent Chinese dragon), down the dusty street in an 1850s Old West town with wooden buildings like shops and saloons and a brothel. The cowboy is holding a realistic Remington shotgun with flowers in the gun barrels. The whole scene is painted in dusty sepia and brown tones
