I got the door break down on que working now!

Now I am just struggling with trying to get the key from the cellar, to the foyer, and working... SO MANY FATAL ERRORS

Yes, yes you do spot Toby Turner references, though they are totally accidental! XD

Glad you like the videos! I cant wait to do yours and Mr. C's when you guys are done!

What can you see wrong?
