Help with choosing correct parent

Which of these posts should be the parent, post #5550162 or post #5550225? post #5550162 is a combination of two images made by the artist (I haven't uploaded the Chinese girl's), while post #5550162 is the full-body version of the German girl. Not sure which takes precedence really, though I lean towards post #5550162

Usually the one with every character present is preferred, even if it’s cropped, especially when there’re multiple individual character posts, since they can only have one parent.
