This one with Skye Nova was made a little later that evening, up on a walk-around area. The sky mixed well with the flash, although you do notice that the sky gets dark very quickly, and the flash output needs constant adjusting to be on par with the sky brightness.
Skye Nova is wearing a corset here, beautiful but making it hard to breathe. 🙂 Fortunately she lasted until the sun disappeared, after which we nearly got locked up inside the building. Luckily the guy who closed the door did another round before going home to sleep, and we managed to get out.
