Yup, those are better, and I also agree that #2 is the stronger shot.
In #1, the background is definitely better, pose is fine - but there's something bothering me just a bit about the outfit. You've got the nerdy glasses, but then the tight cami and leather jacket. Then you've got the provocative look of textured tights with denim shorts, and yet the shorts are longer than you'd expect for someone who wears them with tights, and she's got flats on. It's like she kinda sorta wants to be a bad girl but is afraid of committing to the look. It's an outfit that looks like something she might wear to class, but it doesn't look like a styled outfit for a photo shoot, if that makes sense.
The obvious choice would be to put her in heels and short shorts and then ditch the glasses, but quite frankly, I'm tired of that cliched vision of sexuality. And the setting suggests you were going more for the sexy but nerdy look? Lose the tights and the shoes, keep the shorts and the cami and glasses and maybe replace the jacket with a loose-knit cardigan that's sort of falling off one shoulder or something?
Anyway. It's late and I need to go to bed so who knows how much sense I'm making anymore
