Just playing around. This is upscaled from 1k to 6k, and then slightly sized down for 4k wallpaper. Was actually very clear, and added film grain made it look photorealistic. JPEG ruined that. Lol
Do feel my iridescent shader scale could have been slightly smaller before warping by cloud shape.
Very nice effect, and cool cloud composition too, actually.
Nice.
Original and well done.
Thats a WOW!-pic! Like!
