Successful here means that I got it on the first try, not after the character was revealed as dead or, worse, after somebody explained it to me.
1. A leaf or petal falls
2. Snow falls
3. Night falls
4. Pretty much anything else falls and then breaks
5. A warrior takes off his helmet and then puts it on the floor instead of wherever it's supposed to go
6. A window is left open
7. There is a crow or raven, or another culturally appropriate animal or flower, just hanging out
8. A person actually says "good-bye" when hanging up the phone
9. A tree is dead in the spring or summer
10. A child's toy is abandoned
11. Somebody has a headache or a nosebleed or a cough
You'll note that none of these things are fatal in real life, but in fictionland the rules are different.
You'll also note that I didn't include "Somebody who has no business making long-term plans suddenly decides to announce their plans to all and sundry" or "Somebody who just left a life-threatening situation declares that they're safe now". That's not foreshadowing, that's just recklessness. Don't do those things.
