Look under the jacked collar on the right and the white shirt on the right. The base game has bad ambitent occlusion here and the yassyslop doesn't know that so it just 'brightens' the areas anyway.
Not to mention the insanely bright lighting on the face from both sides. The original image was lit by a lantern and then a bright off screen magic source.
The yassyslop filter just says "oh that's 2 bright lights? No worries i'll just cover the face in oil, remove all subsurface scattering and hard light it for you! Yass!"
