Yeah, this one's looking pretty cool, even though it doesn't look like you did much besides adding that sweet shading effect.
Purple one still has the best face/neck for me, though.
Also, the way his head is positioned now, hiding more of his leg, it makes it a little harder to tell how his front left leg is bending. Takes away from his pose a little, I think. Then again, in the old one you had that weird tangent that was making it look like his leg was growing out of his face. Maybe you should try adding a little space between his head and his back leg? Even if it's just a few pixels where his leg bends, I think it might make a big difference.
