 - In the cases of low-resolution games' achievements, it can be hard to get a Badge looking good without it looking _blocky_ or _blurry_, in these cases the _blocky_ look is often preferable, so that the images have a _retro_ feel to them.
 - You can make each Badge have little rounded borders like an actual Badge or some extra spiky corners for emphasis or a king's crown for difficult ones. Its your design. It should visually represent the achievement itself, or hint at the location in the game for secrets.
 - Matching to the game's art style works well. Google Image searches for "Sprite Sheets" is another useful tip to include some game art.
