Too much sharpness applied and stretched with a lot of light channel.

Thank you for your opinion! Regarding sharpness—in my view, that’s a matter of taste, and there’s no arguing about taste. About the light—is there somewhere I can read more? I don’t understand what you’re referring to.

Colors are limited due to the Luminance channel—it's heavily stretched, likely processed in Siril.
