Beautiful moment captured here!
The most MINOR critique I can offer: I don't know if this was cropped at all but if I could change ANYTHING, I'd probably move the crop so that the left edge is closer to the cab of the truck (?) allowing the viewer to "see" a little more of the woman's face.
I am a fan of shallow DoF as used here, but it does leave me wondering a bit more about the emotion seen in her eyes when this moment was captured!
