i think i would pick number 2 if i had too.
in 1 & 3 i find the bright tree a bit of a distraction.
in number 1 the reflector is possibly too low, casting that hard shadow in the wrong place in her face.
love the expression in number 3 but the combination of pose & camera angle doesn’t do any justice to the model. her arm looks too big and not flattering. good light on her face.
i’m not mad about number 2, but i think you could tone down her jacket and add some light on her face. no annoying tree so to me it’s the best of this set.
good job to go out and try things out of your comfort zone. i have never used my reflector and probably should use it all the timeS!!
Mark great first attempt really like the third one a lovely shot apart from the elbow as mentioned.
The shadows ion the face in the first 2 take away from the images as I think they are bait too strong.
as always these are only my opinions and from someone who has never done this type of photography so well done on getting out there.
