Anything you are trying to duplicate would be primarily based on psychic suggestion, so it would typically be somewhat ghostly in form and shape. The image itself might be pretty good, but if you take a close look at it it's definitely not reality, if you're staring at it dead on you can see through it. Basically, you'd be good at the standard kitsune trickery, fox fires and illusions at night, seeing things that might not be as they are or casting doubt on what the eyes see, but you wouldn't really be able to do the straight up impersonations, those abilities are being reserved specifically for human-based Ditto shifters and Zorua shifters so it wouldn't be fair to give those powers to other shifters as well.
