With the potential expanded cast of characters, are you planning on expanding the barn area to hold more? There are six stalls in there already. -- Also, does the plant on the left of the garden only have one animation? Were you planning on adding a second one too it, since the right one has two?
For the barn yes, it will be expanded when there are more characters (currently you can barely fill all the working slots so it's not worth adding more just yet). The pleasure room will also be expanded to have about 4 more worker slots. As for the plant, they should have both 3 animations they can randomly pick from. (they do share the same animations though)
