Please take the follwing in good light, as I mean well :) Postwork, or painting after the render does not "make" an image. You have to start with a good pose, lighting and composition (I could go on with more). I could actually work with the lighting you have, but the pose is unrealistic, unless she's leaning on something. It looks like she's going to fall to her left as most of her weight must be on her right foot and it is too far to the side to support her. Like I said, there's just so much more than painting hair or cloth or whatever it is you want to paint. It's all about the whole image... it's all about color and point of view and balance and... well, much more. And you have to start with something that works from the very beginning. Imagine a house about to fall over. I could paint it, but now it's just a newly painted house, still just about to fall over. Like I said, I don't mean to sound overly critical, but more instructional. Of course, it could be just me. If someone else really loves it, then go for it :)
