Yup I draw Aliens too. I drew this while watching Jurassic park. I just thought the idea of a giant T rex size Predalien would be cool. Named her Princess just to be cute. I didn't draw mandibles on her however because she's quite detailed enough. I didn't want to add more.

Now that I see this old drawing. Her head seems shaped like either a Reaper from Mass Effect or a Squid.
