Aerith (Aeris) Gainsborough, from Final Fantasy VII.
This turned out as one of my favorite creations, mostly thanks to the lifestream base that looks wonderful when lit up, but I'm also pretty happy about how I did with Aerith herself. Modeled both in Blender 2.82 beta.
Printed on the Prusa i3 MK3 using Fillamentum Mukha and Clear Smaragd Green -filaments. 0.15mm layers for Aerith and 0.2mm for the base. The LEDs are a simple "fairy led" strip stuffed inside the hollow base. In hindsight I shouldn't have printed any bottom layers as I now had to cut holes in it anyway to fit the LEDs, so depending how you print this some assembly might be required.
EDIT: Added files to print the tendrils separate, and something... else, that I wasn't sure I should add but was requested enough...
