I´ve been asked lately to take headshots, I specialize on Landscapes, documentary or even fashion outdoor, this is new to me. I don´t have studio lights, for these I used a plain circular bulb, and that´s all... hope to read your comments!
Hmmm...I think you might want to close your aperture a bit more to get both eyes equally focused. I guess it must be difficult to do if your just using a circular bulb. I don't know the focus length of your lens, but I'm guessing pretty wide? Maybe close to 24 mm? If so, you must have been pretty close to the subjects, which only leaves a very narrow depth of field with your aperture wide open. Personally, I probably would have shot at around F8-ish.
