my understanding of Japanese isn't pretty basic, but I always watch your tutorials and learn a lot from them. I'm very thankful. I hope you keep growing and become even more popular!
Im not all too sure myself. And sorry if you have to google translate this But when I see the gradient map, I think maybe some other way to recreate it would be Multiple Layer/Overlay Layer on top with a airbrush then blur? Not so sure if it will work but maybe you can give it a shot 😅😅
