This is a cool one. You've made the proportions for this cartoon really great and she looks like tinkerbell but with that 'modern' twist that so many above me have talked about. Good choice to go with colouring the eyes in blue but with the rest monotone, really makes the attitude stand out.
The last thing I want to say is that I appreciate you not sexualizing (Is that a word?) her too much, the clothing seems trendy, but not slutty or sexual.
