Her expression seems way too forced. She has no eyebrows. The style of anime is supposed to have eyebrows even if the character has bangs. Also, they're no need for the two shiny thingies. Just put one. The right part of her waist seems to be going outwards instead of inwards. A lady needs curves. Her wrist is a little too bended. All though, it's not really a big deal. There is barely any shading, other than the hair, but it's shaded wrong. The shine is supposed to be on the left or right side, not everywhere. Her head seems a bit too big for body.
@Purplebunny: Uh, you don't need to say that. The reference isn't even proportioned correctly....
@Anni: Same goes to you. Honestly, if someone said it, you don't have to beat a dead horse.
For your second try, it's very good! I really love it. 6.7/10.
