Since I've drawn that last panel, I actually came back to the location that inspired me for these sceneries, and lo and behold, those sort of thick wooden short posts that Emile and Noëlle are sitting don't actually look like that up close! I've went on the beach to go and sit on them myself just a week ago and realized that what I though from afar was wooden posts are actually flat gray rocks! 

So either I leave these here as they are, and the comic has a difference from the "real" scenery, which is absolutely fine, OR I modify these pages as best as I can with the power of digital art programs and make them resemble gray flat rocks, which would also be absolutely fine.

... these are the little tiny thoughts I go through as a comic artist.
