Well at least she's hotter in this picture, than in the reference. 
Not only is your comment not critique, I also disagree with it.

* Don't do life studies in a smaller canvas than what you need to show the correct volumes of the object you're shading.
* Fun colors come second, proper volume comes first
* Your eyeballing needs a lot more work. Let me rephrase: my eyeballing needs lots more work, so imagine how much work your eyeballing needs.
* Very nice choice of reference
* There is an emotion in the reference. How would you describe it, and is it the same as the emotion in your version? I know I didn't manage to fully replicate it, how did you do? On which parts of the face does this emotion lie? Let us find it and properly address it.
* Block shapes as if you were doing a low-poly model. No pixel tech until this step is done.
* Hope to see more work by you soon.
