"
because this pokemon look like a girl I want give her a more feminine aesthetic, (yes, I now that some of they are male... but that was corrected with the inclusion of Gallade, I think...)"
Gardevoir can still be male, Gallade is just an evolution exclusive to male Kirilia with a special stone given to them when they reach a certain level.
Gardevoir can be male or female, Galled can only be male.
Awesome designs though, absolutely lovely!
