1. You got some color peeking. Always place a high contrasting background behind your image, and look for where that coloring peeks through. You also have the bottom of the legs peeking a little. Make sure you're exporting as an artboard (which it looks like from your filename). If you are, make sure that you move the fill past the artboard so that it cuts off properly (or snap it to the artboard using Smart Guides; see below).
2. You have some areas that are not properly snapped to others, such as the hair fill going into the face on the neck and the collar, as well as in another couple places. Turn on Smart Guides (Ctrl+U) and use it to help snap nodes onto other objects while moving nodes with the Direct Selection Tool (A). Turn it off by pressing Ctrl+U again, since it will only cause headaches if left on for anything else.
3. The hair lacks curvature at the tips. You want the tips of the hair flowing in a certain direction at all times, instead of flat and stale. Use the handles more at the tips to help achieve this.
4. The buttons are fairly faded. A good trick to fix the coloring is to select one of the buttons, open the Appearance panel, shift click the Fill icon box, click the drop down on the top right, and click the HSB scale. Then add Saturation or reduce Brightness to alter the coloring. I reduced Brightness by 4 to make it darker (next to top button).
5. You picked a good skin color within the appropriate range, but for future reference, keep skin colors within these values H: 25-35, S: 15-24, B: 95-100. Less Saturation means paler skin, and more means a richer yellow skin. Depending on the character, you may want one to be paler or richer.
