I purchased Animorphia Colouring Book for myself this week
It is definitely a book for more experienced colourists as the images are very detailed and there are some images that require you to finish drawing them and add doodles of your own! There are also a lot of double page images so these are not quick 1-2 hour colouring projects and you can expect a large image to take a week or more to finish.
The book itself has images on both sides of the pages but the paper is quite thick and cardlike so there shouldn’t be any bleedthrough
I will do a more in depth review at a later date once I have completed a few of the images to show you all
For now here is my Work In Progress with my own doodles completing the image
