This photo was inspired by a picture I saw of the bust of Nefertiti. I tried to give it a Creole/Caribbean twist.
Key light was a strobe in a 7" reflector bowl with a grid and diffusion on it. Rim light was a speedlight in a small flashbender, with the diffusion panel, shaped to minimize spill. Backdrop was a wooden door.
Your posing is perfect. I'd recommend dodging the highlight on the lower back of her hair, otherwise the lighting is perfect too. Well done! Gorgeous model as well.
