Happy Tree Friends: Illustration and Artwork is a book about concept art of Happy Tree Friends that was originally released in Japan on 2015. It contains many pages with a lot of pictures of the characters with different looks and doing different things. Some images have been used for the merchandise, DVD covers and some from different episodes, but others appear to be more interesting, like the Turn Around Art and Original Pictures.
Turn Around Art and More!
There is Turn Around Art for every character, but Lammy & Mr Pickels. The pictures were likely made before they were added to the series, possibly around the time of the TV series, but Lammy & Mr. Pickels still have other art dedicated to them.

Artwork
This part of the book includes additional art, like art that has unique styles, art that includes multiple characters and also comics.
Original Pictures
This part of the book shows off early sketches of some of the characters and other sketches as well.
Character Pictures
These pictures seem to of been the finalized versions of the characters that were made after "Spin Fun Knowin' Ya" because Giggles has her marking on her head and her buck teeth (when she is showing her standard expression), and Toothy does not have his two long hairs on his head. Giggles and Toothy look different in "Spin Fun Knowin' Ya", so these pictures must have been made after.
There are pictures of Cuddles, Toothy, Giggles, Nutty, Lifty, Shifty, Handy and Flippy.
Other Pictures
Here seems to be two early versions of Cuddles and the other being a side view of Handy.
These pictures seem to show some concept ideas for different episodes, but ended up never being used. Also the cheerleader picture shows The Mole's full face; this is the only time that his full face has been shown.
The picture of Handy falling off the ladder and landing on his tools and nails appears to have been been one of the original concepts for the episode “Shard at Work”. But was changed to him biting the bulb and falling with the glass from the bulb in his mouth instead.
This picture appears to be a concept for the Complete Disaster DVD cover, with Petunia and Splendid (who were missing in the final version) included.
And this image seems to be an early version of the cut out that can be seen in "The Process" from the Happy Tree Friends TV Series Volume One DVD Bonus Features.
