Airy,
Great expression and posture! I would not worry about the bokeh as no one should notice unless that's all they look for bokeh alone in a photograph. The subject should distract attention from such a mundane detail. Now if you are in the market for a new 50-60mm fast lens that would be different.
On my computers L's legs and the right side of her face are too cool. I'd try setting the WB for the shaded areas of the photo and let the background go warm.

Dave, I agree that the bokeh is a minor trouble compared with the two ladies and their backpack.
Concerning the WB, I hesitated a lot (my monitor is calibrated, so your perception matches my intentions, or unability to decide). First thing is, arms and legs are in the shadow, but her legs are simply less suntanned (Northern France is not California). So it would make sense to harmonize those tones in PP. Question is, what's the target.
I know that cooler skin tones are generally not appreciated. One reason might be the association of tan with healthy, successful, "in" young adults (older ones would even get orange-colored). On the other hand, pink / magenta is a more common target color for infants (responsible parents do not expose kids to blazing direct sunlight). My impression was, the "girlish" expression would ask for pink, rather than tan. In the end I left auto WB settings alone. Still, the mismatch between arms and legs, while reflecting reality, is somewhat disturbing. Maybe I should consider an intermediate solution, using proper masking (warmer legs, cooler arms, re-balanced face).
