So every Dark-type pokémon should be pitch-black?
And Houndoom's mouth got smaller, it's pretty clear.
Not sure if anyone has mentioned this, but what happened with Seadra!? Horsea and Kingdra look great, but Seadra looks extremely disproportionate. It'd look better if it's torso and maybe it's head were a bit bigger--it's fins and tail look HUGE!
