I was looking through my hard drive for something Christmas-appropriate to post here, and came upon this black and white version of the drawing I did for the official 2007 Mirage Studios Christmas card. I don't think I've ever posted it here or on my TMNT blog, so...
The idea here was to create a believable Turtle head-shaped door knocker looking like it was somewhat crudely cast in brass. (The door knocker idea was probably meant to evoke the one which played an important -- if brief -- part in Charles Dickens' classic "A Christmas Carol".)
I'm not sure if I succeeded if making it look like metal, but I like the overall look of the drawing. One thing I wish I had spent more time on, at least in the design phase, is the part of the bandana which is meant to be the surface upon which the striker of the door knocker hits -- if you glance at the drawing quickly, it kind of looks like a big tongue.
If memory serves, the finished card featured computer colors by me and some added snow effects by Eric Talbot.
Merry Christmas! -- PL
