I thought this was done very well! It's probably simply because I'm not used to seeing Wendy. I think she is my favorite character. It helps that there is a lot of emotion in her body. I especially like seeing the red lines. It shows good anger.
The shading is done quite well. It's a pity you never made more of these cartoons. They really were funny! I can tell a lot about her personality just by this. The mouth is done well too.
