I have created a coat-of-arms for the tribe I belong to in Tribal Wars. The tribe is called Day of Judgment. I think I captured the motif pretty well.

I started out with the coat-of-arms for the American Heraldry Society, then completely erased the shield section, leaving only the laurels intact. This gave me the desired “clean slate” of a shield with a nice border to start with. I colored the entire shield red, then added some shading to give it a nice three-dimensional look.
I then found a cartoon image of the sun, which I erased the face off of and cleaned up a little. This is meant to represent the “day”. After that, I grabbed an image of a warhammer from the game World of Warcraft using a utility called WoW Model Viewer. The hammer is meant to represent judgment. As a bonus, the hammer has a sun on it, too! The laurels are meant to represent peace, which is what we are striving for with our neighboring tribes.
All in all, I think it turned out rather well.
