Someone told me my digital art looked too clean and it clicked

I posted a fantasy landscape here a few months back and a comment said, 'Looks like a video game asset, needs some grit.' They were right. I was so focused on perfect lines and smooth textures that everything felt fake. I started adding custom brush strokes for dirt and subtle color shifts in the sky, and it changed the whole feel. Anyone else get stuck making things look too polished and have tips for adding more life?
