I really like the emotion and expressions in this picture. It really adds to the effect and the style you have and the eyes are simply gorgeous.The lineart is smooth and consistent, and the little details in the picture(like the dandelion) really make it an adorable piece.
Now, I know you can't update this picture on the rules of the contest, but there are a few things I want to point out so you can be aware of it in the future-
While most of the anatomy is great, the anatomy on Edna's arms is off,mainly because the location of the elbows is not visible, and the marking further down the body makes it look like that's her elbow instead.
You might also want to add more tones in the background behind the sun, and the clouds could use a little work.
As for the shading, the shadows on the tip-top of the grass are unrealistic because the lighting from the sunset is hitting them. Shadows would be further back in the image if that was the case and the highlights would be where it is closet to the light source(the sun) instead of towards the foreground. (that would only be possible is the sun was completely over head, and then the shading and lighting would be accurate.
I like this piece,though and the style is very unique, so please don't delve to deeply on this.
