I for one really like your minis. It is great to have a quick encounter to drop into a session and you do a good job of hinting at lots of good adventure hooks. The only thing I would like to see with this one is some way of handling the Rot Ravens attacking the son. Do you see it as just a combat, but then it would be nice to have some stats for the boy. But that can be hard to balance, if he is strong enough to fight it is too easy, weak and he gets killed off quite soon. Some other mechanism, like x number of rounds, maybe make it more obvious to the characters that there is a countdown...
it is a good encounter.
Thanks!
