So last night I was re-listening to Session 16 and, I must say, I think my "mottled" Ungoliant outfit could really work with an emaciated Ungoliant. I couldn't possibly draw it, but I can easily envision that costume being skintight and sexy and confident in season 1, and then loose, hanging and baggy almost, in season 2. If we were making this for realsies, we could make her 2 different costumes, identical looking, but of different sizes, to help make her look more famished.
Also, I colored in the "final" Arien costume, and designed on a whim an Aredhel hunting garb. Enjoy!
