I have an interesting question for you guys. How do you decided which world when making a crossover picture?

It really depends for me on what kind of crossover I'm doing but its usually from on of the movies the characters are in :)

Depends on the picture I want to make. For example, in my latest Merida/Hiccup pictures, I choose Merida's world when her super curly hair is let out (so I don't need to crop her hair ha ha ha), but I choose Hiccup's world when they are riding Toothless and she's wearing her white bonnet. Sometimes, if I want to make a story like the Wounded Lion, I place Belle and Simba into Pocahontas' world.

Same with others. It depends on which is more appealing or appropriate for the image. :)

It depends on how hard a character is to cut out or whether or not I already have cut outs of that character. E.g. - Belle is fairly easy to cut out, so I usually place her in someone else's world, as seen below.

I’m not sure.
