Wow seriously 5.3 ? Hardcore underrated in my opinion.
Really love the blue. Good highlights on the right spots and overall nice contrast. You could boost it up more with blacklining around all the different parts to give more definition and an overall even cleaner look.
The NMM works as well. The lights seem to be on the right spots and the amount of contrast to make it work is there. Next step would be smoothing it out more. Especially on the egale it is a bit to sketchy for my taste. Use some more edgehighlighting as well.
The face looks pretty good and I like the textured highlights on the hair.
You could have worked out the base a bit more. Nice start would be some more shadows on the edges of the stone. Add some vegetation. The yellow green spots on the stone in the same color as the leaves aren't such a good idea. For grease I'ld have picked another green tone.
Sadly the photos aren't that well either. They are a bit blurry and a bit grainy (to high iso value maybe ?).
But all in all still a nice piece. Keep it on ;)
