nice though may want to cover which is more stable in each form the 1,2 resonance form being more stable due to the carbocation stability. You get both products but not in the same amounts. Showing it in more steps also might be good draw it with just the H attached and the Br alone. More steps is always better I am finding when I teach. (also may want to show why without the assymatry adding it on the other double bonds is the same, not everyone will see that right off.)
