Short update today, since I don't have a lot to share. Had various head aches during the week which made it hard to focus on things.
I did fiddle around with Zara's reference image though, here's what they look like currently:
Zara Alternate Clothes
Tweaked the skincolor slightly, but I'm not sure if the lip color fits any more now.
Made adjustments to the face. It's a lot harder to make an appealing face digitally than when I draw traditionally, huff.
Thoughts and feedback are welcome, as always.
I've sketched up new reference images for Zoo, Lollo and Psycho Girl as well, so we shall see how they turn out later as well! I have a feeling that picking out skincolors for them is going to be another challenge too.
