i'd say she's a traditional PK, for several reasons:
1- she only has one split in her tail rays, that narrows it down to either a VT or PK.
2- her anal is very wide, but also very short, and her dorsal is rounded rather than oval, which suggest a PK (even before their fins grow to full adult size, you can get a feel for their shape)
3- her ventrals are wide and paddle-shaped, rather than thin and toothpick-like, which you'd expect from a long-finned fish.
she also looks like either a "classic" or "wild type" as far as coloration, judging by the red rays and blue membranes in her tail, and the blue speckled dorsal fin.
