This LoRA works pretty well, although I found it helped to push the strength up to 1.25 or above with some checkpoints. The placement and pose are usually quite consistent and accurate. The cardboard often comes out with a greenish tint rather than brown. There is sometimes white space on the edges of images, creating a tall narrow image with blank space to either side.

This LoRA works best with anime, comic, and cartoon checkpoints, but it can also work with realistic. Nice effort, but it could use some refinement.
