I drew this one in a real hurry, but oddly it doesn't look like my worst work yet. Glass half full guy says that means I'm improving.
It's really difficult to separate player knowledge from character knowledge. For instance, I usually know the immunities and damage reductions of a monster I'm fighting, but often it doesn't make sense for my character to know that only a cold iron wrought weapon can damage a certain creature, or that skeletons don't take damage from cold spells.
