Some sketches of the "Easter pig" in the story, as well as some of the older sketches I found that I did a couple of years ago. I wish I could add more but either they were on paper or I cant find the files.
I struggled with whether to have the pig walking on 2 or 4 legs, but I prefer a more natural form as I don't want to overly anthropomorphize his character. One issue with this was how to make him carry a basket in his mouth. If his head was too low then the basket would be tiny, so i've tried to make sure there is enough space between his head and the ground. I may explore having the basket on his back, but that might affect some areas of the story.
@Mara-Price Yeah I think I hope I can help retain her cuteness and oldness when it gets to color.
@Pamela-Fraley @MattBaker @Georgios-Christopoulos @Coley @LauraA thanks everyone. I hope I can provide something useful for others 

Old sketches. I was originally planning to have mother nature look more like the upper left characters, but I wasn't happy with the proportions, and felt something cuter and simpler would be best. Also, I wanted to use the pig in the bottom right, but it felt too Warner Bros cartoony and lacked some of the maturity that I wanted in the pig:
