I finished this months ago but for some reason I forgot to post it...
I actually really liked how this design turned out! It is similar to the original concept art version but with some elaborations. Mainly the gold ribbon and bow at the empire waist and the beading on the bodice.
It's so beautiful! You keep mentioning the original concept art and I searched for it on google but couldn't find it, is there somewhere I can see the original concept art?
