Face changing script seems to not be working?

if game.Workspace.Episode7.Parent == workspace then
	while true do
		wait(2)
		script.Parent.FakeHead.face.Texture = "rbxassetid://15637705"
		wait(0.1)
		script.Parent.FakeHead.face.Texture = "rbxassetid://277939506"
		wait()
	end
end

When I test, nothing happens..

The reason why this wont work is because it needs to refresh first, If it's a player then do

script.Parent.FakeHead.face.texture = ID
script.Parent:LoadCharacter()

or if it's a NPC try

script.Parent.FakeHead.face.Texture = ID
script.Parent.FakeHead.Parent = SOMEWHERE -- Anywhere lol
SOMEWHERE.FakeHead.Parent = script.Parent
