From the artist:

I really did like the Bad Guys movie! It was great, fun, energetic! The style was bouncy and fit the theme perfectly and I loved everyone's character designs........ except for Diane's... I think they could have improved on her design and the dresses she wore in the movie. So I came up with couple of mock designs

The first one is pretty obvious. She looks more like a dingo then a fox in the movie so I made her more of a red fox. I think the deep crimson markings would have fit better with her "Crimson Paw" name, and a good reason to cover up her arms with opera gloves! Her diamond, instead of a ring, is a broach on her waist and all the triangle pieces of her dress are pointing to it. (foxes are usually associated with triangles)

The second one, Diane as an artic fox. You see red foxes all the time whenever there is a fox, and I think a sexy white artic fox would have been an amazing design choice. She's cool and mysterious. She's "white collared" now and but still wears gloves to cover the "blood on her hands" (which incidentally could be another reason why she's called the Crimson Paw. The white and blue color scheme is usually associated with good, pure characters so it would have been a wonderful red herring! I wanted her dress to be more of a secret agent James Bond dress since that's essentially what she is. I know it doesn't fit with the Lupin the 3rd aesthetic that the movie has, but you have to admit, she's pretty! ;w;
