I’m partial to adding an incantation and a stern warning.
Edit: It occurs to me that the Animagus transformation doesn’t require an incantation either, so that’s not a general rule about free vs. non-free Transfiguration, and it’s hard to imagine that an incantation like Crystferrium (“Furniporcis”?) wouldn’t give away the direction. Just the warning, then.
Yes, the big thing that’s missing is the warning not to try to copy her example. Anything else can be chalked up to the Professor’s leet transformation skillz.
