Having looked through their items updates announcement, there's some weird stuff going on with their pixelling. Looks a lot like a lot of them don't understand about the light source.
Like with this item.
All they've done there is pixelled the wings on one side then flipped them over and added them to the opposite side, so the light is completely wrong all down one half of it. Seriously lazy to do that. Also the stuff is pillow-shaded which is a massive no-no.
