I've tried the tool, and it works great! Have you thought about giving some control over how product image is separated from the background (in some cases product images could be tricky - have rough edges, be not contrast enough with a background)?
I also loved the idea of typing tags to create a custom scene, have you thought if that could be made with a moodboard-like approach? For example, it could help for beauty product to select a custom grass (maybe from the library), add few flowers, make adjustments of where the product is located etc.
