I think you do make a pretty cool Spartan. That expression either means you admire him like.. "whatta guy," or "Alright, we get it, keep yer beard on." I wonder how many Persians you also killed as well? Good job mate.
Actually they did a really bad job at cutting you out. In one scene I think I saw your arm for a second and in another one it was your leg. Also in the last scene where they show the 300.000 soldiers you are in the 53rd row the 516 one from the left.
