no, you're right - if you zoom into the photo, Pearl definitely looks upset, and Darcy appears to be comforting her.
but yeah, i'm sure both girls will treasure the memory of being dragged out specifically for a photo shoot, forced to pose in a random field wearing their tutus for endless posed photos taken specifically for content - a photo shoot which will undoubtedly have taken hours, with Louise shouting commands and ordering them about, taking multiple photos until she managed to get a couple that she deemed instaworthy. and they're not even visually beautiful, aesthetically pleasing photos, as Louise has selected a dry, barren wasteland of a field, with a casual sprinkling of wildflowers. it's a truly strange location - and that's not to mention the inappropriateness of Louise plastering posed dance photos of her daughters on the internet, despite a Darcy previously expressing that she didn't feel comfortable having such photos shared, as it was all too much pressure - so she's sharing photos of her children without consent, while simultaneously working as an ambassador for the NSPCC.
hy would either Darcy and Pearl "treasure" a memory of their mother photographing Pearl in distress while her big sister tired to comfort her, while their mother captured the moment on camera instead of stepping in to console her youngest daughter?! a treasured childhood memory of their mother, yet again, prioritising content over the emotions of her children.
