Hello! I am a painter, illustrator and graphic designer. I have recently finished one project that is similar to yours, so you can check the style of cats illustrations that I've made. If you like it we could do something like that, but I am also very flexible and can do any type of illustrations for your needs. Here is the link of my profile, so you can check my artwork and also illustrations of cats that I am talking about. The project name is "Cats for the card game".
