I wrote yesterday whole post about it, but mysteriously it disappeard... on the other hand I was falling asleep back then, so prolly I deleted it myself unfortunately.
Anyway I was posting my previous message before that dwarf hunter's edit, and I was pretty sure he meant face expression, which is not actually scary much, at least to me.
As for the paint face I'm already writing explanation :
Fristly, I removed paint becuase I had to have whole image of face in general, and then I noticed that it actually shares Tauren's features, and so I started to work on it to grant those cat forms unique troll - like face features.
Secondly, Tigers got some special features as we know- stripes and white underbelly, and to me putting colorful stripes on stripes from fur looked kinda messy, as if it was too much. the balck srtipes from fur are already nice, aesthetic addition to face. But around eyes are some white (and one teal) spots to power-up the impression that they're frowning upon something/ glaring.
I also didn't wanted the face paint to dominate the face. On current cat forms it was being use to distract from flaws of model, here I wanted to expose uniquness of absolutely new face. (that's why I also changed the tusks, so they weren't hiding face).
And lastly, I also wanted people to notice that I changed nose and generally whole face. Tigers kinda got flat nose and thse stripes from face paint were optically making nose part of face look shorter, and trolls were supposed to have long nose. But I guess I shoul've tried with wrinkles. Yet, I though the glare expression was good enough.
Hope, that will somehow justificate myself.
