Very nice light and color grading is top notch. I think I've read some of your posts in m43 forum and there you explained that most of the post production is done with Lightroom only. Is your workflow still the same?
Not the Miss Marple I remember from the TV series.
I don't have any problem with the negative space on #1. However, I found myself distracted by the window in the upper left corner. The negative space let's the viewer's eye explore. Ideally, you want it to wander back to the subject. The window kept pulling me off the edge. Maybe it is just me. :-/
I didn't really notice it until I read the comments, but I agree: the background on #2 is rather bright.
Great shots. She's a looker and you brought out the best and maybe a little more. Really nicely done.
Now... it may take a little time for her to really become Miss Marple, who we generally consider to be a more, um, mature woman. But it will be worth waiting around for it!
