Well, you took some finding, but VERY nice indeed... As I said to an artist friend once, I'd give my right arm to draw as well as you!
He was James Allington, who I knew from illustrations for Ford Transit Parts Catalogues, but who drew some fabulous cutaways of cars...

Sadly, he's retired to France, now, but at least I sat in his Testarossa. The REAL one, before it was sold and he had a replica made...
