The skin and Royal Thunder may feature both purple and yellow [ or oddly close shade or something], but the only difference is is that it's swapped in primary and seconday color terms, so it's not technically similar.

Also, I think the skin is quite nice, but have you tried using different small decorations to it? Possibly like a moon to get a better reference to Sailor Moon aside from the fact that the Luna cat silhoutte has a moon on her forehead.
