I'm loving this challenge you have decided to participate in!
Sadly, I don't know most of the characters, but your drawings indeed are always so nice and you have developed such a "soft" style when dealing with fantasy characters, something perfect to convey "fable!". It is a pleasure to discover new ones, waiting in my dashboard.
Do you think it would be possible to add a link to the character in its owner's page so that is possible to see "the original style"?
Is this Dorothy Gail who has replaced Ozma as ruler of Oz? The sunflowers might have been the giveaway.
Dorothy Gail was the little girl in the story who traveled to Oz in her home via tornado. There have been other stories of her as an older girl or young adult returning to Oz. This image looks so much like her at a later age.
I knew the basics of Wizard of Oz (Dorothy, Toto, the lion, tinman etc) but I don't think I ever watched the movie... I didn't know there were stories about her as an adult. Interesting !
