Anatomía de monstruos XD [LINK]
An illustrated guide to Japanese folk monsters by artist Shigeru Mizuki. Full of gems like this:
The Kuro-kamikiri (“black hair cutter”) is a large, black-haired creature that sneaks up on women in the street at night and surreptitiously cuts off their hair. Anatomical features include a brain wired for stealth and trickery, razor-sharp claws, a long, coiling tongue covered in tiny hair-grabbing spines, and a sac for storing sleeping powder used to knock out victims. The digestive system includes an organ that produces a hair-dissolving fluid, as well as an organ with finger-like projections that thump the sides of the intestines to aid digestion.
Concept Art - Pacific Rim
By Flex McCool
Pacific Rim is a 2013 American kaiju movie directed by Guillermo del Toro. The movie plays off of traditional Japanese giant monster movie concepts but adapting them for an American audience. The movie was met with a large amount of positive critical acclaim. The end product featured a visually dark and shadowy world highlighted by neon glows of vibrant color (such as in Hong Kong). The concept art displays the film team’s experimentation with color, light and shadow in an attempt to reach the optimal effect. The movie was extremely well adapted for 3D in the end but the design all started with this concept art.
Concept Art - Star Wars: Aliens and Creatures
The book titled, "Star Wars: Aliens and Creatures" contains amazing concept art from the "Star Wars Original Trilogy" portraying the concepts of (you guessed it) aliens and creatures through their development.
