These are some portraits I shot on Thanksgiving day - all were handheld - natural daylight from a window behind me..... thanks for any comment / critique
Canon 1D Mark II
Canon EF 100mm Macro
Some softening applied in Photoshop
I'm with steady here as I think the Aperture was too large hence the apparent shallow DOF.
You've captured well the expressiveness of the eyes, I too think the skin tones look a tiny bit warm and a pose at an angle would have narrowed the young ladies shoulders and perhaps made a nicer pose.
The tight crop and lighter background help lift her clear of the wall as well.
