A user pointed out that the portrait in the Orphanage entrance hallway changes between day and night in "The Funeral" chapter.
By request, I've extracted the textures.

Unused 3D Model: blood81
I think this blood stain is unused. I’m not sure what it was intended for. If the numbers indicate a chapter, then it would have been for either the “The Little Princess” or “The Gingerbread House.”

A little bit of Halloween exists in Rule of Rose on a texture in the main hallway of the Orphanage. Unfortunately, it’s only used for the chairs. I can’t find a jack-o'-lantern anywhere.

Here’s that misplaced texture behind the door in “Rear Gate.”

Originally, I assumed this was for the Showers door, but its texture name suggests it was meant for the hallway in the Gingerbread House.

This creepy texture is used for the shadows in the Orphanage dining room (shown in green). I don’t think the words or drawings are visible anywhere.
