<https://s.mj.run/3LnSq23dkiw> Create a high-resolution pixel art scene inspired by a solitary figure painting a boundary on a vast, grey backdrop, but make it creepier and add more color. Show a lone figure in a flowing white gown with long dark hair, standing against an empty, eerie background. The figure’s arm is outstretched, holding a black paintbrush, painting a thick black line that forms a partially completed large square. The background should have unsettling, shadowy hues and pops of vibrant colors, like dark reds, purples, and blues, creating an ominous atmosphere. Add subtle, ghostly figures or shadows in the background to enhance the creepy, haunting vibe.
