Placing a part on the character's head?

I'm trying to make a script that creates a part when the "R" key is pressed.

Everything works fine except that the part's position would not go on top of the character's head.

local baseplate = workspace.Baseplate
local player = game.Players.LocalPlayer
local character = player.Character

if not character or character.Parent then
    character = player.CharacterAdded:wait()
    print(character)
end

local function Fire(actionName, inputState, inputObject) 
    if inputState == Enum.UserInputState.Begin then
        local part = Instance.new("Part")
            part.Parent = workspace
                print(character)
                    part.Position = Vector3.new(character.Head)
-- How can you also add an offset so the part is 10 units above the character's head?
    end
end

game.ContextActionService:BindAction("ChangeColor", Fire, false, Enum.KeyCode.R)
