François Remmen : Here's a list of things which can be improved. I've also included an image of what I based the commentary on, most were found on a Facebook group dedicated to the tracks history. You can enlarge all the images by clicking on them.
Don't take it as criticism. I would just like to see the track as close as possible to how it should be.
Trucks in the paddock are too modern. Actually, there weren't that many either as most cars stayed in local garages and were driven to the track. The paddock was mostly filled with road cars.

At Eau rouge, the are two signs missing on the left, the Ferodo logo is a modernised version (and it should be placed on both sides of the road).

This is the correct one:

The logo next to it is a variation of this one, with the head of Stirling Moss on it:

At the top of the hill, the KLG logo should be this one (but with inverted colours):

There should be panels hiding the parked cars on the road to the left:

There's a Ford logo before the grandstand:

And BP on the inside:
The trees should be closer to the track from this point upt to Les Combes. I also think they should be a bit taller than now.

These people would never be allowed to stand there, and the treeline should be lower:

After Les Combes, the road on the left didn't exist and I think the house wasn't there either (looks like a bunch of trees instead):

I don't think Ferrari would have a truck parked there, and neither would Lotus at the exit of that turn. Actually there would be nothing parked there because it's an escape road.

Some help to get the signs right:

These are the Esso, Castrol, Lionoil logos you can use as a base:

There was no advertising on this building:

Approaching the start, no one would be allowed to stand there:

The Enica banner returns at La Source:

Caltex should be replaced, that brand was never marketed in Europe.

Some shots of the actual signs:

The text on the pit building is wrong:

Spelling error on the Pirelli ads (here and all around the track), it should be "Le pneu qui a fait ses preuves".
