In terms of overall look, I'd have to go with A. If you want to show off light piping, C.
B is just too bright.
As a professional tanuki (I'm a Japanese mythological animal, and a good luck charm), I have an alarm clock built into me somewhere. I also look like a stuffed animal. And you thought your life was tough......
I am looking to show the toy off as clear as possible. A 20 MP camera should do the job. I am just not used to working with a toy so white, which is why I am using a black box. Also why I am asking for other sets of eyes.
