Nice start for this "slice of life" Sim's story : the screens are colorful, the poses and expressions adequate, and most of all you've got a nice comic layout to ease the read (and which allows you some creativity for the backgrounds). The plot seems not to be overly complex though, but visually there were some interesting ideas. That being said, while the french language seems impeccable (and with a rather good text centering),  I think you're limiting your audience quite severely by choosing to publish only in french in an english-speaking site. It's already hard enough to draw some attention if the story is good/enticing enough, but if you go for french only, it's doomed to stay rather confidential. That's why some authors went for translations, and so we've either got bilingual blogs or straight english written stories.

Anyway, good work overall. ?
