Let's pick Heather's Expression!
- Disgusted/sassy 161
- annoyed/sassy 79
- mocking/sassy 69
So the artist is really good at copying the image examples you give him, but if you just say 'sassy' results are mixed. I was about to do just that without sending a photo reference, but I've since learned my lesson. That being said, i'm not 100% sure what qualifies as a 'sassy' expression myself. I've included a handful of sassy expressions, so we can pick one for the artist to give Heather in the cover.
As always, feel free to give feedback or in this case, drop a link to something better if you're not feeling any of these.
