A princess who was a frog - competition

Couple of illustrations I made 2 years ago for a children's book competition for a fairytale about a happy frog who was turned into a human princess against her wishes... (more description under the drawings).

A sad prince is looking for an enchanted frog to kiss...

The frog-princess runs away from marriage.

The frog who doesn't want to be a princess anymore meets a jinn.

The frog princess explores the human world with her best friend.

Happy End? Not really, as princess's best friend is about to be catched by another prince...
