Relevant TODO:

// TODO: Render the specialist effect (like a smiley for entertainers)

Original game example, the entertainers have smileys:

We already have the art assets configured, just not associated with the citizen types. The citizen types should have all the details configured already:

• Prototype/C7Engine/C7GameData/CitizenType.cs

  Lines 26 to 43 in 8b7643a

  	// The contribution, in gold per turn, that this citizen makes towards
  	// luxuries/happiness.
  	public int Luxuries;
  	// The contribution, in beakers, that this citizen makes towards teching
  	public int Research;
  	// The contribution, in gold per turn, that this citizen makes towards
  	// the treasury.
  	public int Taxes;
  	// TODO: Figure out the details of how corruption is reduced by
  	// policemen.
  	public int Corruption;
  	// The contribution, in shields per turn, that this citizen makes
  	// towards production.
  	public int Construction;
