Nice website, you did a good job with most of the design! Really like the combination with beige/black colors and the photos😊
Here are a few improvements:
The text "Trouver le courtier qu’il vous faut !" seems to have too much space between the lines.
Make the header links a bit bigger.
The photos don't have the authentic feeling, like the one "Zoom de la semaine" seems a bit too extreme. I would switch some of them to more authentic ones.
