Did a quick google translate on this and a following (text only) post by the artist... something about being busy or just taking a short break from drawing the last day or so due to work I think?
Yeah, unfortunately this artist's pace is regularly interrupted by work (or that's the reason given for delays 9/10 times), so not terribly surprising. This particular Otomore picture was made as an apologetic gesture for the lack of updates the past couple of days, but they said Day 29 should be tomorrow.
