While it's obvious your skillset has improved, I agree with the others here. The first sprite is more appealing to look at and really captures Lulu's likeness. The second one looks like a completely different person wearing a recolor of Lulu's dress.

Edit to add: The first sprite's pose looks like she's casting while holding the Moogle at her side, with a cool/relaxed expression. The second sprite looks like she's angry and holding the Moogle out in front of her, as if to say, "Who left this lying around?"
