Pen and ink drawing painted in Photoshop. Sorry, but this drives me up the wall.
Addendum: Boy have I got some interesting comments on this one. O_o
For the record, I'm angry at the *professional* artists, toy makers, ect. who are still doing this. No offense is meant to the "Jurassic Park" fandom (hell, I'm *part* of that fandom, so yeah). You don't have to stop drawing "JP"-style 'raptors just because of this comic. (But don't knock feathered maniraptors until you draw a few yourself. Feathers are ruttin' easy to draw anyway.)
Do note, there is an Important Addendum
Also, please please please
READ THE COMMENTS before posting. There's a lot of great information down there that couldn't be expressed in a picture smaller than the size of a sheet of paper. Read this article as well
, because Brian Switek explains it all better than I ever could.
