I think you should keep the "Flipping the bird" rock...it's gives your tank some attitude. I could see myself indulging in the taste testing of hopps, to the point where I might think the rock was trying to pick a fight with me. Could turn out to be very entertaining for the folks of Canreef if you had a video camera, and put yourself in the situation
Like someone said earlier, I believe aquascaping is always a work in progress...you get your foundation pieces where you want them, and then you're always building off them, or moving pieces around trying new things. You can always find faults with rock work, but in the end, it's what makes you happy when you look into the tank.
