So, here are my entries. And I'll talk about them a bit if I may! :3
When I think of MWKs, I always think of the black kit with the green/blue tail in the MWK cover, so for me it felt a bit like a mascot. So I could only see it fitting for a mascot's design to be dark based.

My first idea was to color it like an aurora. It would be dark based, resembling the night sky, with the blending colors only on the tail, but that seemed too plain, and I decided to add a bit on the body too. The design is still simple, though. Basically you just paint a few lines with the color and smudge over it with 'blender', so I think it's not too hard to replicate. And her eye is purple with a bit of the greenish color.
For the other one, I didn't have an idea until I started coloring. I picked a dark purple-ish color for the base when I though "what about a Milky Way Kit with a Milky Way theme?" and then I started trying with the whites until I got what loosely resembles a marble fox, then I added the galaxy on her leg. For the tail, I searched for images of the Milky Way and used those colors as a guide, which I think blended quite nicely. Oh, and her eyes would be differently colored, with the right one being reddish and the left one being blue.
As for their names, I didn't think much and just dubbed them Aurora and Milky Way (or just Milky).
Hope you like them! :3
