Yes the technical aspect has definitely improved but the main thing that I love about the new one is it's life. The figure feels alive, the earlier one is just a few pixels arranged in a humanoid shape, the 2nd one is a real character, her eyes shine and her costume sits on her frame fabulously and the body language feels like she's just lifted her arm to go "oops".
The only downside I'd say is the GLAM peach background lets it fade away a little (I viewed it on a white background and it popped a lot more) but that's not exactly your fault XD
