[oc] Sera Illustration rework

Heya!

i decided to rework this project to update it to eevee next cuz i've been struggling with my other projects. i learned quite a bit with this one, especially when it comes to rendering refracted materials! also the lens flare is just a picture on a plane with emissive lol.

I feel a bit more comfy with the new renderer now so i'm gonna get back to work on my Lady Dimitrescu illustration <3
