Very cool faction! I think the bee icons on the Preserves should be a little larger though, it took me a while to even spot them. If they were centered in the building and the same size as the draw icon it would definitely help.
In the second of the Queen's command would you be able to move the Keep? That seems potentially dangerous, but it is a cool idea.
It seems like it might be hard to get preserves out on the board as it takes a turn to convert conservation tokens to preserves and you can only place one token per turn until you have more preserves.
