We started modeling Edair first in part because he is a very straightforward character. The problems we are trying to solve in modeling are not related to how cool the character can look, but to how we have to build and export characters in Maya, then into Unity. For such purposes, often the more straightforward characters are better because they're "neutral". Chain mail and leather not make you hop out of bed and scream OWOOOOOGA! but they're things we're pretty likely to have to create and they pose actual challenges for us when it comes to building and rendering it.
Someone compared the painted portrait of Sagani to the line art of Sagani. You can certainly compare them, but they're made for different purposes. Line art drawings like the ones Polina has done will probably never appear in the game. They're made as reference. Any coloring done after the fact is mostly just to give a sense of volume to the character and his/her gear. The painting of Sagani is a great portrait and we'd like all of our portraits to be that good and in a similar style -- but no one is going to build Sagani from the painting of her. She's in a cool pose with a determined expression, but you're mostly looking at her back and side.
I understand that people want to see more art, better art, and more unusual art. We will make it. It has always been our intention to do so, but a lot of the problems we're trying to solve right now are logistical, not quality-related, and while paintings like the one of Sagani or even the wallpaper of the whole party are exciting and beautiful, they don't necessarily help us build the game right now.
Thanks for all of your feedback.
