So this is rough sketch of Porcia. She was the one who trained Kiki and Gaia.
They call her a "Witch" either because she's such a strong and talented Psychic that its almost magic or...she can be a real 'witch' bitch XD
When I first though of what kind of Gijinka I first look at the list of Psychic Type pokemon and the Grumpig appealed to me.
When designing Gijinkas I like to design their body types according to the Pokemon's physique. Like if a pokemon is thin I draw the Gijinka thin, if the pokemon is muscular I draw the Gijinka muscular.
So I wanted to design an elegant, voluptuous and saucy woman.
And then I realized she looks like a cross over between Miss Piggy and Cruella DeVille 0___O
Well she's also a criminal she deals in black market and gambling business
