I think, this "no, leave me alone" pose is the perfect pose for your little princess. It shows, that she has a strong mind and will make her way. Very good artwork.
One of the cutest pouts I've seen :) I love her tiara which shows that she is an official princess. I like the effects used to make this look like a drawing or illustration. Good and clear with nice details. She'll appreciate this image later in her life. Great job and adorable princess :^)
I kept seeing this image of yours periodically ... and one; it was a good choice of images to convert as the changes you made emphasize the 'mood' and 'feel' extremely well.
And two; there is an immediate visual interest for me ... as I love to sketch as well.
Thanks for sharing your 'Pouting Princess' with us. She's still a cutie though, regardless of her expression.
