My original tumblr post was here. This illustration was made by an artist working under the name of Crik and posted on ver tumblr with the comment:

This is the illustration I made for trinquette weekly challenge,I wanted to give her a retro look but with a twist, new look therefore I pictured her fully dress, which is kind of new for the character, i made the background match her costume, colors, play with yellow and green, as a reference to the sci fi, alien atmosphere of barbarella, and as a tribute to the old barbarella comics, it was hard but fun and interesting.keep working.
