Sindragosa the frostwyrm queen

sindragosa from world of warcraft: wrath of the lich King in humanoid form ( this is how I imagine her in humanoid disguise , I'm not sure if undead dragons can do this too, like red, bronze, green and black dragons does, but I wanted to draw her as an undead elf with dragon horns, basically a very undead looking high elf death knight because blue dragons usually take human, elven and gnome disguises)
