Finally, I'm done with this manga.
I didn't expect it to have been so long and tedious to put together, but at least I learned quite a bit from this experience.
Depending on the reception of this work, I might continue it.
I know what my mistake was this time: having chosen a character with such a complex design. Twintailed Girl is not only difficult to draw (especially her hairstyle), but her overall design is very detailed. I took a long time drawing her hairstyle and her sneakers.
This May I will do something "lighter": 2 or 3 pages with Pink Bodycon, which has a much simpler design than Twintailed Girl.
