Childrens short stories

I started a few paintings last week- one of a cow and another of a pony. I was working with a new medium, which I had never used before. Its ink and then some overlays of acrylic and then some oil. Very interesting. They both turned out very child like so I am going to use them with my children's short stories. Let me know what you think?
Have a wonderfully creative day.
