CharmeC: technically all YoSD are considered limited. I really don't like the acrylic eyes that come with them so that's the first thing that goes. Tenshis usually are released with HG Glass eyes. The Disney Yos had some experimental eyes that look to be urethane called Dollfie eyes. The fullest YoSD started having HG glass eyes.
My one pet peeve I can spend a lot of time fiddling with eye placement. Some molds look good with side glancing eyes. Others look nice with slightly upward glancing. I avoid the stare straight deer in headlights or vacant stare.
Did you also switch out the hands in addition to wiring? Yo hands usually have separate wrist balls.
JennyNemesis: Faceup enhacement should be the beginners class, beginners painting is somewhat a misnomer... I find it easier to add to something already there vs starting from scratch. I usually end up with uneven brows, lol.
They teach reshaping existing brows by adding extra hairs, adding temporary pastel to cheeks and eyes, adding lip lines, adding gloss and removing eyes in the enhancement class.
