So it seems the source is just slapping on the character over the background. Normally, this works out fine, but for this one, the picnic basket (which is part of the background image) is positioned so it would be slightly in front of her leg. Putting the character on top thus results in this:

Looking at official art of this online from other sources, it appears the leg is positioned properly behind the basket. That image might have been made just for promotional material, but it's also possible the Spine animation assets (which has the picnic basket as a separate element) were used instead.

I didn't notice this issue with the previous images, but I'll stick to the character layers and not push my luck. And just to be safe, I'll make the character layer the parent for all of the previous uploads.
