Here are my favorites that started in 2020! ^_^
1. Necrotective by @dasruedi
Amazing art, lovely humor. The worldbuilding and story are very intriguing and I can't wait to read more of it! 
2. Coin Operated Clone by @vancitta
Love the atmospheres of this one. Dystopian future stories are my favorite brands of science fiction and this one is no exception. Plus, Sai is adorable <3
3. Survivors by Paula Edith
Post-apocalyptic stories are another fave of mine, and this one is no exception. It feels like a TV series and I love that the setting is not your typical big city
4. Regicide: Lilium by enigma.re
Seriously, check this one out. It's a silent comic, so everything is told by images, which are beautifully drawn and simply gorgeous to look at 
5. Necroholic by Brian Lee
I love the style of this! And the premise of the comic is just great XD I'm... not quite sure if the story is on hiatus or not, though, 'cos the last update was in November, but it totally deserves a mention
