i'll just give you personal opinion on this one.
i like the skin tone and color better on the first one.
i like the eyes on the second one.
i like that you widened out the hair on the 2nd but it's now too coarse.
i'm guessing you're doing a dodge and burn technique here, but i think you went too much dodge on the camera left cheek and the camera left hand.
the 2nd one is a little more moody, which i sort of like but the color tone puts me off a bit, especially when compared to the original. had you just lit it differently for the mood rather than the dodge and burn (if that's what it was), then i think it would have come across better that way.
so, aside from the hair coarseness, this is almost entirely subjective. overall, i prefer the 1st one, but i like points on the 2nd as well and it's almost a toss-up if i had to choose one over the other.
