Character development + Cow

Here are some compositions using a cow as a character. I used reference from this childrens book space artist model:

Ramu Moon

I think the colours work quite well, and I tried to copy the style of the artist a bit with my figures:

From here I thought maybe I could just use a cow instead of a cow and human in space, to make it easier for the children to interperate the story a bit more, rather than having multiple very different looking characters.

I then thought of possibly having two cows, as I needed two characters since the text says "WE make a ship" not "I". Two cows makes a party
