Digital-pencil side view sketches of Zero (Isos design), a nervous bust and a more determined three-fourths fullbody.
Zero sketches
September 5, 2012
Zero’s part of a full Isos sketchdump. I can’t find the original file for this so the quality’s kinda mediocre.
IIRC the green used to look transparent or semi-transpaent on deviantArt’s layout at the time. RIP.
