Raven Eating Remains of a Skull Idea

Hello,​Been thinking of getting a raven on my right shoulder but a little bit skeptical of placement of the raven and if the raven should sit on top of the skill or not.​Idea 1: Large raven is placed on right shoulder and faces towards my chest, eating an eye of a skull from above right nipple​Idea 2: Raven stands on top of skull on right shoulder with its beak into the skull headI want the tattoo to be black only, realism style and preferably reasonable sized which I why I am also a bit skeptical to have a skull sized correctly with a raven on it :/​Any ideas or tips?
