The "mana" colors for the card game are white, blue, black, red, and green. It would be nice if the mana symbols could be incorporated in the design. You can see them here:
The header image needs to be 775 x 120 pixels.
The splash page background image should be at least 1024 pixels wide (possibly wider, but not any smaller) and at least as tall as it is wide.
There must be some "dead space" in the background image where we will put login and signup forms. By "dead space", I just mean areas where we can have these forms without blocking anything significant in the graphic.
We may alternatively just have some text and a couple of buttons (Login/Signup) on the splash page, which would require less space.
We want the graphics to be dramatic and bold (this is like a fantasy warrior game) . . . if you can include some fantasy warrior characters, that would be awesome. Not too cartoonish though -- "almost lifelike" is what we're looking for.
Here are some "idea generators" . . .
The header image can be derived from the background, but it's not a requirement . . .
