I switched out the lines for a simple megaphone, that wouldn't be mistaken for any of the other officer roles.
Beth suggested not to have it filled, as the other icons were line only. Another small thing we changed were the upper line thickness on the events logo for it to read better as a calendar.
Additionally, from the feedback given we made the Icons twice as large. I personally prefer the smaller versions, they were clean and delicate but we work to a client so bigger it is.
