Original post here. This image was researched by Bacchus at ErosBlog as part of the “Γ commission.” The research was originally published at Hedonix as “Γ 034 – Spacegirl Tentacles. Here is what Bacchus found.

This artwork is by Japanese artist Kurono, whose Facebook page identifies him (?) as an “artist, illustrator, and graphic designer in Japan.” He has a web page here, which offers this additional information in English:

After having been employed as a designer of videogames, and as a designer for a record label, KURONO is currently doing free-lance artist in Tokyo, Japan. That style is to begin with a cute character and then poison it somehow with an eccentric and unexpected twist that morphs something normal into something abnormal. Blending cute elements or characters with weird, poisonous twists can produce fascinating artwork.

KURONO has done various designs for Tees, CD jacket, flyer, poster, and more. “It is my hope that many people will look at my stuff and find the unique and interesting element that lies within.”

Kurono has an extensive profile online at Behance, which is a sort of online portal for freelance artists and people seeking to obtain their services. This particular artwork is shown there under the title Spaceage Mystic Order, and is the first in a “series of self-produced posters”. Several more posters in the series can be seen at that same link. It appears from photos on a couple of gearhead blogs in Japanese that these posters have been marketed at Japanese auto/bike shows. A version of the artwork is also planned to feature in an upcoming set of stickers.
