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.
