Araven. The hair-ExEq combination and use of stickers over the eyes and in combination with the clothes cohesively support the presentation of a crow-commanding battle sorceress. I suppose I would've liked to see a little more color, but that's only nitpicking. Well done.
Honorable mentions, in posting order:
@brucege's
Lolys (lolis? lollies?): Looks fun! The outfit gives a clear impression of an adventurous tinkerer. Plus points for introducing the fruit of your creative faculties as "Ok so this ho is..."
@NeclordX's
barbarian: I think I remember a previous version of this CaS from back in SC5. Anyway, he looks great in SC6! Clever use of the patch sticker as a big scar adds a ton of uniqueness to this character.
@Gaahl's
Gaia: Despite use of Aval coat and armor, their placement on a slim frame makes a great example of a winter/armored assassin character. Very nice.
@Alexandra's
Samira: A close second for me! I don't understand what's Eastern European about her, to be honest; I get more of a "Xena: Warrior Princess" vibe, but she is beautiful nonetheless.
@Norik's
Zeldor: I think I remember a previous iteration of this CaS too from SC5. It's because of the shoulder pocket sticker. Take it as a testament to this design's uniqueness.
@The_Weasel's
metallurgist: Another favorite in this round! I very much get a Mad Max kind of impression with this one, due to the rusty gear sword, frayed coat, and Warlock Slacks.
