I guess so. The preview can be anything sorta related i'd say ;)

It made it through the public queue  so it may have more to do with my own personal interpritation of the rule than the way the communty understands it.

Mmh yeah... I try to sum up what the art is in a cute way. This preview was an ant nest. If it's a problem ill stop.

Thanks for the advice, ill try it out sometime ;)

"7. Your small file (preview image) should match the detail file (full image)."

The ant is well drawn, and the merged style makes it even more original. If i were you i would put more contrast between reds, on the other hand.
