Here is a little 'logo' I made to represent 'Death by Fruit' in its new style.
Here are some backgrounds made to look like classical Greek vases.
Land
Mount Olympus
Dome - Outside
Dome - Inside
The Underworld
Future
I used a rough textured brush on Photoshop to try to emulate the rough texture of a vase. I wanted to stray away from it looking too smooth or digital.
I had difficulty with the borders at first because I made them too thin, trying to make sure they didn't obscure from the characters. However, there weren't visible enough. So I made the borders thicker and more obvious and I feel they work well without deterring from the scene.
