This is my collection of versions of Cars 3, Toy Story 4 and Finding Nemo 2 logos that some people have made (see my Cars 3 Possibility blog for my Cars 3 idea.)

Toy Story 4 logo made by Pixar 3, which actually does look great.
Finding Nemo 2 logo made by Pixar 3
Cars 3 logo by Gray Catbird, which is good is used in my Cars 3 blog, as well as The BABAMStudios' Cars 3 blog
