ViewportFrame Camera CFrame on model not zooming in?

Hello,

I have a local script within a ViewportFrame as its parent. The script's code it:

local plr = game.Players.LocalPlayer
local plrs = game:GetService("Players")
local char = plr.Character or plr.CharacterAdded:wait()
local hum = char:WaitForChild("Humanoid")
local vf = script.Parent
local vfc = Instance.new("Camera", vf)
vf.CurrentCamera = vfc
local m = Instance.new("Model", vf)
m.Name = plr.Name
for k,v in pairs(char:GetChildren()) do
	v:Clone().Parent = m
end
local h = m:WaitForChild("HumanoidRootPart")
vfc.CFrame = CFrame.new(Vector3.new(x,y,z))

I am trying to make it clone the player's model into the ViewportFrame, which is done successfully and works since it is viewable from the ViewportFrame. However, the Camera's coordinates, see 'vfc', would have to be (0,115,25) for the camera to remotely close to the player's model, and even then it's still pretty far away.

My first question, is it possible to zoom into the player more on the ViewportFrame? And my second, if so, how and why doesn't the current system I have work?

If my code for cloning the character is incorrect too, please tell me!

~ Thank you.
