I left the scarf because it already looks great from the other redraw, but I wanted to go over the expression a bit. Your expression already conveys sadness; now it's up to you how far you want to push it. I would make the eyes bigger and rounder. Then I moved the mouth and the nose a bit to give more of a pouty face. I also added more highlights/tears. I would look at some references of exaggerated sad expressions (especially in really stylized cartoons). Great job!
