Ace of Spades (Pixiv Fanbox)

I wanna test out doing the bunny girl so today I wanna upload this first before finishing the 15th vol. Starting with the Ace of Spades. Spades gonna be Human, and their primary color will be black. I am still thinking if they should use different bunny costumer or not tho, my first thought is that they all gonna have their uniform which will help differentiate each symbols
