Finally got it done! This didn't take as long as I thought it would :)

So with Grookey's design, I referenced off of band uniforms. With Sobble's, I referenced off of swim suits. And Scorbunny's was referenced off of sports wear. I gave variety in body types and such between the three. Like Sobble has a skinny body type and pale skin and Scorbunny has a muscular body type (cuz fighting type Pokémon) and tanned skin, stuff like that. They also have different eye shapes from one another.
