Very nice older Maggie, I really like the headband, top, jeans and that pacifier necklace plus the "Silent Power" on the side was pretty good in describing what Maggie is in the series: Silent Power, no speech, but enough force to size up to the talking characters.
In summary, very nice character design, coloring and drawing.
I like this one a lot. The 'Silent Power' was a great touch. I see you went with a more Lisa-esque hairstyle, rather than the one that Maggie had during the Lisa's Wedding episode. Once again, keep up the superb work.
