Oh, I do like the evil gleam in her eyes. Just out and out glee. Someone who truely enjoys what they're doing.
Funny tho, I seem to like the lighter version better, like it was taken with a flash, but I think that's also my particular weakness for fair skin ladies. (makes my knees wobble.)
Excellent work! An extreme, unrestrained pair of faces! The emotional state of these girls is easy to read! And the torture rack is effectively detailed: the wood-grain surface is quite convincing. I too favor the first version of the picture: those skin-tones are a luminous, pearlescent fantasy!
