Heya,everyone!Here's Tanzanite's official designs ^^
Old form(took this form when she served Yellow and Pink):
A simple gem,made kind of like a acrobatic despite being a entertainments type. The smile is emotionless,almost robotic like. At the time,she was a mixture of showing emotions and not showing emotions. She has a petite yet athletic build. My favorite part of her is definitely her boots,and her arm rings.
Current form(took this form during the rebellion but was reverted to her old form upon rejuvenating herself):
Has a more genuine,happy smile. Not much was changed,but she has a more cute,genuinely cheery appeal to her. Despite still not understanding emotions fully,she evidently shows them more often(not noticing that she does). A little more "soft cute feminine" build than previous form. Overall I really like her current form more. It has a unique charm to it ^^
