Stegosaurus lines

Another piece of that something I put together for a little cousin's birthday. Five dinosaur illustrations, this one featuring a Stegosaurus and a generic small theropod. Maybe Coelurus or Ornitholestes, dunno. Did it in ink and left it plain because it's meant to be colored, so he'll get to choose how the animal will look like in terms of color and skin patterns.
Guess you can color it as well, if you want to.
