Hmm... Pretty good, but there's a couple of things you could improve on.
1. Her eyes seem a little big for her face. Her face needs to be elongated a little bit or else proportions don't work.
2. I think Ai's eyes (... homophones) are blue, not green.
3. Hair. It's much better than last time, but the right side still looks slightly off. I think that bit of hair sticks out more.
4. Legs. I think they're too long. The torso should be longer, and her lower legs shorter. Bodies are always difficult. XD
5. Eye placement. One eye is bigger than the other and they're not even... I'm trying to fix that problem myself. (why isn't this eye working right?! Argh! - that was yesterday...)
6. Collar bones. They shouldn't be that long. Usually people don't spread them out much farther than halfway to the shoulder.
The rest is really good though... Your style is different from Gosho's but it's still quite nice. Keep practicing! (I hate being such a critic... )
