The Mind's Dilation

Collan was an average kid unlike most, he had a few disabilities here and there, he got bullied and hurt like many have before. But he found himself with the innate talent to create things in his head without problem, going as far to create an entire universe based on the few characters he had made. The only problem arises when he awakes one day and finds himself now trapped within the same worlds he took so long to create, and finds that his world has now changed from what it originally was. He now finds himself in unfamiliar territory surrounded by the threat of death, consumption, and even the presence of an unknown creation he doesn't know of.
This is all an original story, I've been working on it for at least six years, I know some bits of the story won't be amazing and there's gonna be cringy and bad parts all over, so please add in some criticisms! I have reference pictures for all the characters and I'm also working on an OC sheet that kinda describes each of the characters, soon to be released!
EDIT: I have a few chapters already done and published ahead of time, but the rest will take time as I write when I've got free time, thanks to school and work free time isn't a common commodity
