The unofficial rules for winning a screenshot contest
1. Use a zoom, tilt, sparkle, or border effect. Odds are you lose by default without one.
2. Clever use of emotes are good, using any event item reward from the repeat quest is better. (Coins)
3. Nobody cares about triple triad, and astrologs are better off showing their cards in front of anything else apparently.
4. Should've worn bunny ears.
5. Should've been riding a mount.
6. Should've been in front of an arcade machine instead of behind a triple triad table.
7. Don't have what you need for 4-6? No problem! Just strike a pose with a weapon and follow rules 1 and 2 (and 3 if you're an AST) and you might just win anyway.

and lastly

8. Never consume half your body weight in salt before viewing contest results lest you lose and take in that final grain that makes your heart stop. I'm typing from beyond the grave. I need a rez. Halp.
