So expected it was unexpected.
Aww... i was expecting the guy to shoot a portal below the guy and have him trapped in an infinite portal loop or something, instead of just dropping in from the portal. Since you're using such an innovative concept as the Portal Gun, make sure the kills are as creative. Like using portals for momentum or dropping a guy from somewhere high using portals.
Besides that, the actual animation and portals looks pretty good, so go for it.
P.S. Your response to the below comment says "bad english is one of my two languges (english is the other)" is that a reference to the fifth element?
