Another "anatomical" sketch about Dren from "Splice", maybe this won't be the last

The human skeleton on the right (male) is there just to see the differences.
Dren skeleton was not so hard to do, a part the fifth missing finger on the hand, her skeleton is from the forehead to the legs basically human.
The problem was drawing legs. Not because they were hard, but I went out crazy with proportions.
The reason is that in one backstage video The actress who plays dren (Delphine Chanèac) said that to make her feet digitally, they used a section of her arm, from the elbow to the wrist, and they modified the hands.
But the problem was that the legs seemed to long with those proportions, so I spent one hour searching pictures of Dren feet, thinking that I was wrong XD
However, I hope you enjoy it

However thank you
I think you're right, her legs are actually a second pair of hands, so they should be similar in structure with her arms.
However as long as i can remember she never "rotates" the feet, she just moves them up and down. You know like a bird or a dinosaur if we wanna make a further comparison, so i guess she don't need bone structure such as the one in radius and ulna, that is what you're talking about.
But mine is just another point of view
1. ur right about the legs. doring the dance seen and when she was younger u clearly see the fimer is shorter. if u look at how the leg bones of a bird or raptor r it will give u a better idea of leg praportions.
2. u missed the wing and dorsal finn bones.
again this is awsome and ill definetly be checking out more of ur art.
And I know that there are mistakes, but about the wings and the finn, as I've already said a bone is a rigid structure and can not be flexible and disappear under the skin such as Dren's wings and finns do.
So I thought that they are composed by something else, like cartilage or a flexible tendin structure, so I didn't drew them
