The only thing I can comment on really is that you use a lot of French cultural references, while the site is in English. Not sure how many Anglo-Saxons know about Spirou, Babar or Mafalda, or even the word BD.
It's a thought-provoking experiment though, representing those iconic figures without horizontal information, just vertical.
Also, I'm not quite sure about the parts where you start breaking the rules by introducing changes on the horizontal, I think it deteriorates the message quite a bit.
