I think I screwed up my TweenService thing?

The script below is Localscript and is in StarterCharacterScripts.

-- Services --
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local UserInputService = game:GetService("UserInputService")
local TweenService = game:GetService("TweenService")

-- Variables --
local plr = game.Players.LocalPlayer
local Char = plr.Character or plr.CharacterAdded:Wait()
local Remote = game.ReplicatedStorage.RemoteEvents.FireBallEvent
local Mouse = plr:GetMouse()

-- Settings --
local Debounce = true
local Key = 'Q'

local Animation = Instance.new("Animation")
Animation.AnimationId = 'rbxassetid://2593868235'

UserInputService.InputBegan:Connect(function(Input, IsTyping)
	if IsTyping then return end
	local KeyPressed = Input.KeyCode
	if KeyPressed == Enum.KeyCode[Key] and Debounce and Char then
		Debounce = false
		local LoadAnimation = Char.Humanoid:LoadAnimation(Animation)
		LoadAnimation:Play()
		
		-- View --
		local player = game.Players.LocalPlayer
		local character = player.Character
		local torso = character.HumanoidRootPart
		local mouse = player:GetMouse()

		local ev = mouse.Move:Connect(function()
		character.Humanoid.AutoRotate = false
		torso.CFrame = CFrame.new(torso.Position, mouse.Hit.p*Vector3.new(1,0,1) + torso.Position*Vector3.new(0, 1, 0))
		end)
		wait(.5)
		ev:Disconnect()
		character.Humanoid.AutoRotate = true
		
		Remote:FireServer(Mouse.Hit)
		wait(2)
		Debounce = true
	end
end)

And the script below is what I tried to make player turn more smoothly.

-- Services --
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local UserInputService = game:GetService("UserInputService")
local TweenService = game:GetService("TweenService")

-- Variables --
local plr = game.Players.LocalPlayer
local Char = plr.Character or plr.CharacterAdded:Wait()
local Remote = game.ReplicatedStorage.RemoteEvents.FireBallEvent
local Mouse = plr:GetMouse()

-- Settings --
local Debounce = true
local Key = 'Q'

local Animation = Instance.new("Animation")
Animation.AnimationId = 'rbxassetid://2593868235'

UserInputService.InputBegan:Connect(function(Input, IsTyping)
	if IsTyping then return end
	local KeyPressed = Input.KeyCode
	if KeyPressed == Enum.KeyCode[Key] and Debounce and Char then
		Debounce = false
		local LoadAnimation = Char.Humanoid:LoadAnimation(Animation)
		LoadAnimation:Play()
		
		-- View --
		local player = game.Players.LocalPlayer
		local character = player.Character
		local torso = character.HumanoidRootPart.Position
		local mouse = player:GetMouse()

		local ev = mouse.Move:Connect(function()
		character.Humanoid.AutoRotate = false
		
		local part = CFrame.new(torso.Position)
		
		local goal = {}
		torso.CFrame = CFrame.new(Mouse.Hit.p*Vector3.new(1,0,1) + torso.Position*Vector3.new(0, 1, 0))
		
		local tweenInfo = TweenInfo.new(5)
		
		local tween = TweenService:Create(part, tweenInfo, goal) 

		tween:Play()
		wait(3)
		ev:Disconnect()
		character.Humanoid.AutoRotate = true
		
		Remote:FireServer(Mouse.Hit)
		wait(2)
		Debounce = true
		end)
	end
end)

Yep it didn't work. I don't even know how TweenService work in the first place. I need a solution for this thing to work.
