Really nice! The face and expression are good an the themes are to my taste. To bad that the full story is split among 3 gallery. I would have preferred starting at the beginning. You should consider re-upload all the tree part in a single gallery.
Also, do the author have a patron, a blog or some place where he publish his work?
Because chat bleu is a pretty shitty name if you hope to be found through Google.
If found that the other gallery of chat bleu, snake games, is missing the most intresting part (or at least most of its content). I found it here : https://rule34.xxx/index.php?page=post&s=list&tags=chatbleu&pid=126. If the link do not work, just search chatbleu on rule34.xxx and go to the end of the gallery.
