Hi, I love the map!
the shore is very detailed, with cliffs and details that make it look real. For instance Etretat is wonderfull!
however, north of Saint Martin, no more cliff but only a sandy shore.
First of all the beach should be made of stones, but I undertand that I am being picky!
But the issue is that the shore should not be flat as it is represented. Youcould take the example of Criel sur Mer, north of Dieppe.
And there is this very creative pyramid of Sand on 49'58''34 N 01'12''35 E.
Thanks
