I need a comics art reference folder, anyone kind enough to share?
A folder is not necessary.
Read The Noble Approach by Maurice Noble, it'll solve any doubt you have about props and backgrounds.
When I make a comic I starts with a script then move to make storyboards/thumbnails, after that I make a list of things I need to reference like poses props backgrounds etc, I look them up on stock photo sites or google images, make simple studies and design the stuff that needs to be designed and then I can move to actually making the comic
I do have a reference folder with lots of photos but I never use it, I only keep it because some stuff is cool.
