Ideas for the sniper scope scene

Just been thinking on different ideas on what we could use for the sniper rifle sequence. One of the ideas I had in mind would be that of the squirrel interrupting the hitman as he took aim on his target. As we thought about using the squirrel for the claymore scene I thought we could also use him to firstly make his appearance in the sniping scene. One of the reason I thought this would work is because the squirrel would cause the hitman to stress out after the squirrel had accidently triggering the claymore mine, thus resulting in the hitman making a more forceful approach to the targets door. Back to the sniping scene we could have it that as the hitman takes aim on his target, well have a camera shot of the hitman taking aim when out of nowhere a nut comes flying and hitting the hitman on the head resulting in him wasting his only shot. We could have a little mini controversy between the hitman and the squirrel which could end with the squirrel interrupting another assassination event but in return the squirrel loses his life
