I've just been browsing your deviantart gallery, and I see you've also made a larger detailed sprite of the same character. You should post that as well.
As for this sprite, it's very nicely done, and would look good in one of your oasis scenes with some of your other characters. I do have one little crit however; I think her neck is too long and she would look a lot better with her head lowered by 1 pixel to correct this.
Lovely job. I often prefer vibrant colors, but the desaturated colors against the black outline really work well together.
Very cute, I love the desaturated pink on the pigtail :)
I love your really minimalistic pallete! It gives a great look and feel!
