Try Wandering Witch: Journey of Elaina. Or you can also try Secrets of the Silent Witch. These two are both light novels.
As for asking for advice on how to make comics and write them... just do it? There are no fancy rituals or pre-existing conditions you need to do in order to draw your own comic or manga.
I say this with love, I assure you, but you really need to start now regardless of your skill level. If you're already good at it, awesome! If not, well, we have to start somewhere, right? It's only by being bad that we'll see on what needs to be improved and work towards that improvement.
And yes, that means being open to feedback, too.
My tip when receiving feedback is to feel your feelings, sleep on it, and then come back to it with fresh eyes and perspective. It's normal to be initially defensive when getting feedback; every creative knows this. But it's also through feedback that we'll grow. You can choose which feedback resonates with you, and put aside those that you don't need.
Good luck!
