"more Grimm-like grimm masks" and then you have less Grimm-like grimm masks. So you can choose how Grimm your Grimm masks are. Sorry. I thought that was funny. I'll stop now.

I don't see the similarities actually. I mean they both have one pair of eyes (oddly enough) but Goliath is more round, smooth and simple, while WFL is more angular with the eye part extruded. His lines are also sharper and he has lines tightly surrounding the eyes. (making him look eviler)

(I've been looking at these white plates with red lines more than I should. I need a break)

The only thing I know for sure is that Adam's mask is a recruit mask with red lines. Of that I am sure.
