so ... what worked and what didn't ?

Just from a character standpoint, I'd suggest a bolder, more aggressive pose projecting strength, confidence and power. This pose is passive. Wonder Woman should never be passive.

The shadows in the hair are blocked up.
The eyes look like you tried to correct their focus in post.
The exposure on the skin is a bit dark.

Well, she sure looks like she is wondering!

Not feeling the editing and facial expression. Looks like she's constipated. You'll get an E for effort though.  Cheers.

She looks like some one just pushed her backward and she is going to fall
Modeled light on face is distracting
Tension in neck
A stronger crop would be above her elbows
Hair looks washed out at shoulders and lacking detail on top of head [too dark]

Cute touch with diamond by corner of eye
