Here are just a few specific observations I can point out:
- At times, Arthur's glasses seem to shift position, particular when he's facing the camera directly, they almost look too high on his face. I've also noticed his faces seems to be a little longer as well (similar to Marc Brown's earlier illustrations).
- D.W.'s eyes seem to change size, depending on how she appears in a scene, if it's a full-body shot or at a distance, her eyes appear about normal, but in close ups and tighter shots, her eyes seem a lot bigger on her face.
- Mrs. Read's ears are HUGE
- As far as Francine and Muffy are concerned, I think the problem with them as at a 3/4 angle, their eyes appear way too close together, making the rest of their heads and faces look mishapen.
