Interpreting facial emotions is wild. Tiny tiny changes can change the feel so much

Look at the different relative angles between mouth and eyes in each picture. In the real image the angle of the eyes is very similar to the angle of the mouth and therefore the distance between the left eye and left side of mouth is bigger creating a more "shocked" looking expression, like you described it as "Are you seeing this shit?". While in the drawn image the mouth is more angled therefore the smiling is more pronounced.
