Bought these a while back and decided to test how they would work with such mixed lighting in jpg mode, not raw, since many members of Digipets can't save their images in RAW mode. The image actually looked pretty good as it came out of the camera, but I did a Curves adjustment putting the Curves palette white, gray, and black eyedroppers on appropriate parts of the image. The most critical placement is the gray...and I used the lighter gray card. I still had to work on the red of the artificial flowers because I wanted the color deeper and the light green pothos leaves, which I wanted to be darker.
