This is awfully well-designed! The little ponytail (I assume that's still called a ponytail) reminds me of Ryu from Breath of Fire: Dragon Quarter, but that's because I love that game to bits and I'll probably be reminded of it forever now. Other elements are fairly common fare by now, at least in my experience - Gardevoir seems to enjoy ownership of swords (particularly rapiers) pretty often for some reason, perhaps the noble stature or perhaps inspiration from other artists, and I've never once seen a human Gallade without twin blades for obvious reasons. Formalwear also pops up pretty often, again because of the noble stature and also the originals literally wear skirts, gowns and capes.
Prevalence doesn't make me love it any less, though <3
