rule of thumb for funny facial expressions that ren and stimpy taught me and that the TGT panel just reinforces: the less lines you use to sculpt out the contours of the face, the better, and that if you use too many like in all those early 2000s rage face (not rage comics, but the more grotesquely detailed kinds of images that predated them) kind of pictures the expression youre trying to convey gets lost in all those lines. the more there are the less they all mean
