Nice! but i have some of picky stuff to say
the Jumping pose Is weird.
The POI doesn't Really know That ethan is behind him So Why is the Agent Jumping Like he is About to make a last ditch Assassination?
Why isn't he using a silenced weapon? does he have a backup plan once His bodyguards (if he has one) or the whole building he snuck up into hears the loud gunshot? or is he The head of a massive party?
