The linework is a mixture of thin and thick across the board, as you can see in the slideshow. I think it's a great starter book for someone who is new to adult colouring and isn't yet sure what styles they prefer to colour, as there is such a variety available. The paper feels thick, white and smooth, although you'll need to put a sheet of paper between the pages to avoid bleed through. Each design is single sided, so you can use whatever medium you like.
Here's my finished page, completed with Spectrum Noir markers.
And now for something completely different!
Although it is right up my street in terms of dark and disturbing humour, I know it won't be to everyone's taste. What I will say though is that many of the illustrations are so beautifully crafted that once coloured, they would look like really interesting artwork- a definite talking point that's for sure! The book format and paper quality is identical to Awesome Animals, so I won't reiteate those details. Linework again is varied, as is the subject matter from one page to the next.
"There are 49 images. Why 49? Because you couldn't handle 50!"
Here are my finished pages (I couldn't do just one when I saw his other half later in the book!) completed with several brands of alcohol markers. I call them Adam and Barbara (if you don't get that reference, they are the dead couple in Beetlejuice!).
