Hoping to create a fanfiction comic...

[Hato San]

Hiya! Doggo the Collo here xp
I'm currently in depth with creating a long, detailed fanfiction in which I'm hoping to be able to eventually turn into a comic

Is the story, however I'd love to be able to learn, or find some places that can help me learn digital artwork! I already have a tablet and clip studio pro, but I have no clue as to where to start to actually be taught...

I've checked online for online classes... but I don't know how legitimate they are, and just practicing shapes is driving me nuts... (If I gotta draw another cube or sphere or cone... Bafdjakfhjsafjkafkj!!!)

I'm curious to see of perhaps a different way on how to start off, or perhaps even find someone willing to give me pointers! Thank you for reading :3
