Here's a closer shot of the head area. It's the only other image from this shoot that, at the time, was in focus.

This will do nicely
You can see a little black point jutting into the grey of her right eye: this is one of the "horns" that protrude from either side of the vertex. Note also the very high, notched occiput (the yellowish plate atop the head). A. furcifer would lack these horns, and the occiput would be much lower and convex instead of notched.

This is definitely Arigomphus cornutus (Horned Clubtail).
