I need help with art block and procrastinating how dose one overcome it

Id love some help if anyone able to list down some prompt ideas that could help me out?

I think an issue I have with this idea especially I get overwhelmed with big concepts

I very much struggle drawing random things as well I always have to think about it for a long time too

So the world is basically like the adventure time world a broken world but the city kingdom is a cyberpunk dystopian, they have walled themselves off from the animated undead they thought entering the backrooms would be there salvation instead half of there dwindling population got stuck and trapped in the unknown

That the lore I want to work on

But I never knew where to start because there so many moving parts

I've got a list of ideas I still don't know what to do with lol

Any advice you'd give for tackling these without overwhelming myself I do tend to look at these and think ah that's way too much work lol I do really want to explore all these ideas though I just get stuck
