The fire extinguisher is obviously a very literal sign. It shows exactly what a fire extinguisher is meant to do; put out a fire. I believe this has a good sense of unity because all the pictures have a purpose that add to the overall meaning of the sketch. The emphasis on the extinguisher being used promotes the focal point.
The janitor's closet sign is again a very obvious sign. I decided this would be a good way to design the sketch because it has a certain symmetry about it that is appealing. It creates a great focal point as it is equal in dominance.
The exit sign sketch I have created was meant to be a person waving and walking therefore leaving. Although it is asymmetrical, it has a clear focal point. I also believe the arrow and the waving person create a distinctive unity that goes extremely well together.
Since the parking garage sign we currently have is simply a circle around a p, I thought of a more literal stance of a parked car in a square would do the trick. The focal point is obviously the car, which I believe is an easy enough sign to assume a parking garage. The unity of the sketch is simple because it is only one object.
I've never been in an executive washroom, however I think its safe to assume that whomever gets access to it has to wear heels or a tie to work. This sketch is quite literal as all my others, but I think it clearly signifies the executive. I tried to create contrast with the striped tie. The sketch creates one focal point obviously and unifies the item.
