will you still make wallpapers of the month

That I will keep doing most likely, but I will give it away without asking for a donation.

or will the break be shorter than a month?

I don't know, let's see.

when you return, how often will you make your comics? (at least twice a week?)

I don't know. Right now what I see most likely is doing perhaps 4 comics a month, just because I don't wanna kill the comic. At the same time I don't want to feel the pressure of constant deadlines and having to struggle to keep it up thrice a week.
