Depends on D20005. I love icons.
This is the only one I'm a little on the fence about, but I guess you're trying to make these unique and you don't want to re-use fa-key? Maybe fa-clock would work better? This is 100% USDA-certified bike shedding, but I feel like fa-hourglass connotes a thing that the user is waiting on to finish so they can get back to work, not a thing that is already good to go.
