Well the neck is decidedly thicker, the arms a very thin though, they look like sticks (not trying to be mean honey, really) the shoulders are too broad, makes her upper body very awkward. If you make her shoulders smaller, and properly round out the arms (look at your own for reference on how they round out at the shoulder, slowly taper to the elbow, round out at the elbow again, then slowly taper to the wrist) then it would make more sense. And, her thighs from the hip joint to the knee joint would start big and taper thin. As well her hips wouldn't look so small and non-existent (you might want to put more curve there too) And less bosom, it's... a bit much. You have come a long way but you have to practice your anatomy. Get some books, or just look some stuff up online, you'll learn a lot. Cute face, and love those wing hair bands.

You changed it, but I liked the chibi (get that right?)
Well this is cute too. Actually this could be in a baby's room. Violet geeraf. Cuteness.
