I do think the zombie rot dragon moves pretty fluidly, but how someone could read that as "graceful & feminine" is weird lol, even setting aside the instant "graceful=feminine" association for a sec.
I...guess Blackveil Vaal Hazak could be seen as having a...idk mourning or bridal veil...thing going on? Maybe???
The farty barfy corpse dragon is one of my favorite elder dragon designs though, very cool fight. Ugh, now I wanna raise my grievances with the forced gendered armor designs in Monster Hunter...
