Exactly as the title says. Should focus on highlighting some form of change (such as a normal mapped ship or newer model since the last release or have effects that are new over the last release)
Should ONLY contain assets current to the Retail Universe (so no displaying models or effects from other mods)
Should ideally contain a scenario found within the Retail Campaign, but this is _not_ a strict requirement or even a recommendation, but it would be nice, try not to have it be spoiler-ish though.
Should be as clean as possible. HUD elements _might_ be acceptable if a cock-pit view, but otherwise, just the basics.
As little post-production processing as possible. That wasn't properly clarified, so ignore it.
Uncompressed TGA/PNG or original Photoshop PSD (or equivalent).
Must have a 640x480 and a 1024x768 (Or a large enough image that can be sized appropriately for those dimensions). Provide a thumbnail (via imgshack or whatnot) in the post. Do not attach submissions, but rather link them through mediafire/imgshack/etc.
