art...(spoilers all RotE books)

The wings in the book were fairly tiny. If their bone structure is similar to here and they fold up similarly, the wing length would probably be no more than 1-1.3 meters.

Not quite figured out of they are large enough to support flight, but they should be near large enough. Provided that Thymara-as-Elderling is not particularly heavy.

Oh, it might be that Sintara will be able to affect the growth to fit the wishes of her Elderling. Its been proven that Sintara was stubborn but wrong about her own wings, and if there's one thing she still is, it is stubborn and full of pride.
Having the first Elderling with wings is a small thing... having the first Elderling with wings that can also fly, is quite a bit more.

The size of Thymara's wings originally was very small. But that is to a certain degree due to the fact that they had mostly grown inside her body and were limited by that.
Having them outside, where sun can be found for the nourishment that provides as well, growth will increase. Though having Rapscal around to force growth will be even more effective.

If she learns to fly, it'll naturally start with long gliding leaps, then slowly increase in distance till true flight is achieved. Seeing that she's two-legged, she'll also have to learn how to land gracefully.
Regular sunning and flapping will increase blood flow and strength.

It was through a partial re-read that these beings discovered her eye color. As can be seen above, early images has her blue-eyed. It turns out that her eyes are silvery gray.
These beings have tried to get the Elderling bluish glow, but not succeeded yet.
This image shows one of those attempts.



Two images of similar angle, with the latter being slightly larger:



Couple of different angles, latter showing the face better:



By the way, are the claws how you would imagine them?
