beautiful neo universe art! i checked the reference image of 'untethered spacewalk' and tried some things, first i lighten the shadows and adjusted some cast shapes, then gave the picture a more blue/purple tone overall, as the ref image is quite bright and for anime style purple shadow is a bit of a go to. next a soft brush around the shades for bounce light and rim light too at the hair/ear (not asked but i also try adjusting the hair to look more flowy and floaty, and give a bit of stars for background. might help push the outer space feeling) | Artwod Feedback
