Where would these belgian presenters pass ?

[Immanenz]

They do look like Dutch-French mixes. Maybe lighter haired than French in a group, but their facial features are strongly French inspired.
Outside of that i would say they pass better in Germany than in Britain.

[Gallop]

To themselves I suppose, but if you have to make the effort to answer something, well they don't seem to conform to anything, maybe something like some kind of weird Frenchmen.

[Concetta Esposito]

They look broadly european

[Ouistreham]

They all look like what they are, i.e. upper middle class French people.
(They all are from Belgium's French community).
Strangely, the darkest one in the lot displays the most distinctive Dutch Flemish facial features:

[Tchek]

They all look very Belgian/Walloon more than anything else (except 3, Scoriels looks Flemish and has a Flemish name)
Even though De Brigode could pass I guess in the UK, 2 is very Wallon, 3 Flemish, 4 is more pan-euro, and 5 has something French facially.

[Latinus]

A mix of France, NW Europe and continental Germania.

A mix of France, NW Europe and continental Germania.

Yes, fundamentally. In other word: Wallonia.
