Some information you should know
1. This will be my first Doujinshi or Manga in general. I would love some pointers as well!
2. I work in Clip Studio Paint for digital painting
3. it will be a 3P ship and contain incestual relations | Jiro x Saburo x Ichiro from Hypnosis Mic.
4. NSFW Doujinshi

I guess it depends on whether you're gonna be getting it printed. But a good size regardless is to make it A4 at 300dpi.

Or A5. Regardless, doujin usually gave a bigger size than normal manga.
