How would I set the custom character back to the original character?

I am pretty trash when it comes to custom characters, my problem is trying to restore the original character. Here is the code I tried to create:

if game.Players.LocalPlayer.Name == "greatneil80" then
	game.StarterPlayer.StarterCharacter:Destroy()
	game.Players.LocalPlayer.Character.Humanoid.Health = 0
	game.Players.LocalPlayer.CharacterAppearance  = "http://www.roblox.com/Asset/CharacterFetch.ashx?userId="..game.Players.LocalPlayer.UserId
end

I tried something like that,

Custom character image

This is what the custom character looks like.

I tried deleting the StarterCharacter, I don't know if im doing any of this right and don't know how to restore the original players looks.

Any help?

local player = game.Players.LocalPlayer
if player.Name == “urname” then

player.CharacterAppearanceId = player.UserId
player:LoadCharacter()

end

Also sorry I’m on phone.
