Which is the new one? They kinda look the same. >.<; Sorry! ;^;
I do like the top one's facial structure a lot more than the bottom ones'. It's more realistic, though the ear is a bit too small (ears are kinda big). And the top one with the hair is nice too. But the lines themselves look more sketchy in the top one. The bottom ones' lines are a bit more polished and sleek.
And the hand is... really awkward (though it's nice that you tried to experiment with gestures!)
