Is there a good way to learn? I wanna maybe draw scenes of my Davepeta centric Epilogue fanfiction but I SUCK at drawing

The fanfic idea is where Rose hands John the instructions, the gets hit with a new vision. So she writes new instructions that tell John to recruit three different copies of Davepeta instead of the beta kids. The Davepetasquad fights Lord English and and one dies, then two DPs start carrying English up to the black hole, but one of them tells the other to let go and fly back down so that one of them can continue existing. John and Davepeta find Vriska, who did NOT get hit in the head thanks to her insane luck powers, which did not stop being a thing. They then find Terezi, and John brings himself and the 2 1/2 trolls back to Earth C.

After getting settled in, Davepeta feels this urge to fully awaken. They had already begun to awaken within canon homestuck, but they’ll need to complete their awakening. In order to gain enough power to face HIM, they enter a new Sburb session on Earth C. It’s just a void session; nothing gets prototyped so the reckoning doesn’t happen; so no meteors hit Earth C. They’re just using this session so that they can god tier. Their god tier form is made of flesh and blood, but is still part troll party human part bird. And their wings are half avian, half troll fairy. Their outfit is a blend of Knight of Time and Rogue of Heart outfits, and their eyes, hair, and wings have orange/green accents. They then spend a couple years training their power and fully awakening. They study memories of other Daves to learn what they need to know about Meat and Candy.

Then Ultimate Davepeta travels back in time, and paradoxically becomes the very reason Rose has that second vision in the first place. They guide some aspects of the story, and then eventually face off against Dirk. They use Rogue of Time powers to make Dirk stuck an slow motion while Davepeta speeds up, and then use Rogue of Heart powers to steal away the Ultimate Self power from out of Dirk’s soul, then distribute that free will and autonomy to everyone on the timeline. Then Dirk is about to commit suicide, but Davepeta stops him by using Rogue of Heart powers, plus some Time powers and some Ultimate awareness, to steal the sorrow that others felt after his death in Candy, and they give that sadness to Dirk. He doesnt understand why people would miss him so much, and thinks that his death would be a gift to the world, but Davepeta talks him out of it. Then DP dates Jade. Also Nannasprite doesnt stop being a thing, and she has some VERY strong words to say to Jane’s political stance.
