Hey, fellow guild fan.
That actually looks pretty good. You may need to try it out in action to really get a feel for what changes you want to make, if any.
Some good texturing may help to bring it to life.
I’m currently working on a Codex outfit myself and simply putting a basic render together has helped me make some decisions on how to proceed…see here..

From this I can see where I want to add detail into the skirt, bra and trim. The jewels need more depth too.
(I want to make the Codex staff available soon too).
I like the shoulder pads a lot on yours.
