Nice work Farina,
If you look at the Porsche website, under the 997 page, you go to movies.
And you have three movies.
One of them is the genesis of the 997 with all the numbers (I think it's entitled 1 mm).
At the beginning of the movie, you see Harm laggay with his design team designing the car on big boards, the drawings look a lot like yours.
I cannot think of a better compliment!!!
Well done!
