Guardians of the Galaxy Concept Art Shows a Different Design of Nebula's Costume

I really liked Nebula's looks in the Guardians of the Galaxy which is played by Karen Gillan. I just found out that there was even another costume design made for the character by Andy Park that obviously did not end up getting seen in the movie. See the full image below with the caption Park included in his tweet.

"Had the most fun working on #GuardiansOfTheGalaxy My fav was designing Nebula! @KarenGillan2 was badass! #marvel"

Below is what her official costume in the GOTG movie.
