^ Same here, except the showing it to my mum bit .
I really love the movies, so I was eagerly anticipating your recreation of it... and it was awesome.
You recreated it amazingly well... The flaming tire marks, the anim work that lined up with the talking, the car dissapearing, the numberplate spinning, doc looking at his watch, marty holding the numberplate... all the details were there. Its clear you spent quite a bit of time getting this just right, and it paid off.
Great job man.
