I'm having second thoughts on my next tattoo

I want to get a skull but I can't make my mind up on what animal to get. I want either a human skull, crow or T-rex. Im a girl who feels like they're all different asthetics. I like grungy goth stuff. But I also like the silly/cuteness of a t-Rex skull.

Im not asking strangers online "what should I get", I am asking for opinions and different perspectives that I may have not considered like, maybe I'll out grow a trex skull? Ya know?
