Maybe abandoned or disposed of rather than lost? The paper doll idea is brilliant, the models are in character mostly, creepiness is creepy, sadness is sad. I think this setting is very easy to inadvertently sexualize, and the first image starts going this way, imo.
5ft prints in a gallery? There is a lot of detail in these images and I think these details should not, no pun intended, be lost, and in any small size the busyness of both costume and background may overwhelm the image.
