Excellent work! This was one of my favourites in Grand Prix Legends, and I love how you captured the atmosphere!
Having said that, I read through some of the ratings here, because I recalled the track was layout slightly different in GPL.
jokacz is right - the "Gresil" corner was a flat out single apex, which was tightening a little at the end, making it a real "corner of courage" and giving great chance of overtaking on the long straight following, if the guy before you chickened out, or did not get the exit properly.
The "Scierie" corner (the one with cobble stones) is nicely done by you, but before start finish, there was a very fast right hand corner - the "Virage du Paradis" - which in your version is almost a straight line, while in the 1960s, it was also tightening, making it tricky on entry.
To get an idea, what the corners and layouts were like in the different eras, see this link:

And for a feeling of what this layout was like in GPL (which is probably where most people fell in love with this track), have a look at this video:

Again, gorgeous work! If you managed to get that old feeling into the layout, you would be my personal hero! :)
(And probably that of a lot of other vintage racers as well.)
Cheers!
