Yes! Where's the red underlines and diffs? I can see the background banding, but the foreground looks the same at a glance except that some of them look ambiguously "off" in ways that could just be placebo.

You'd think a visual artist would be more interested in visual communication and not just a wall of text with un-annotated photos.
