What's a C14?
So it's Margaret...not Maggie or anything other than the full Margaret. So Steve you are concentrationg on what....the lighting, the posing, some theme.....
The theme could be missing body parts... a foot here, other parts over there....
So lighting....nice....good key and fill....nothing washed out. Tell Margaret her make up is correct also, no reflective high lights from dark eye concealer.
BTW she has great eyes something you can play to them as a photographer.
Posing.....take the white board background and have her scrunch down, back against the boards, wrap her arms around her knees, do a series...head left, head right, tilted.
Have her take off her shoes while sitting on the dock and place them or have her hold them by the straps.
The small package photo, try shooting from a 4 o'clock position with less background. This is a good shot and I keep finding things in the picture. Her right hand placement, her hair following the curve of her neck while other hair hangs up on her forehead. Edit to add....notice the small triangle under her right eye? That's Rembrant lighting....tough to set up.
Delete the last one. Edit to add...just looks to me to be an awkward pose.
