Reluctant to ask since this is a very well executed picture, but how exactly is this an interpretation of Retsuko?

The colour scheme is different, the clothes are different, the accessories are different, the single teardrop is neither present in her ordinary or "metal" mode, and there is nothing about her constitution that resembles a red panda. The only thing that hints at it is the hair - not so businesslike - looks vaguely like her anthro silhouette.



I think I need this one explained. Is there something going on here that I missed?
