The Pastel is beautiful! I like the bell being a different color, but it does look a little out of place with all of that pink, they could add in some spots being a different color to match. The eyes also seem a little to bright rather than soft, but still pretty.
The first outfit is a classic, very simple, very neat.
The second one is gorgeous however! I love the elongated tail, the line markings being the galaxy theme, it all looks like some mysterious alternate universe Kau haha.
And the highland cow!! Look at all that shaggy fur!! This is exactly what this pet needed!
This was certainly a fantastic day, Kaus!
