Dragon Skeletal Anatomy

This is something I've been meaning to do and hadn't gotten around to before...
So yeah, skeletal basics... Unfortunately I'm stupid and forgot the dorsal metacarpals. If you really wanna know, they're the spines sticking out beneath the tail. No real purpose other than for frill expansion or deflective armour... Also, the Haemal Arch should be a little farther down the tail, sorry.
I kinda floated between Welsh Red and Northern Black, which explains having the small narvis and the inclusion of dorsal metacarpals, though I never did understand what use a Welsh Red has for a caudal pectoralis, being a hoarder... It really doesn't even need a latissmus caudali...
Also, only one wing is depicted because who knows how fucking confused I'd get.
