Nice to see you keeping at it. I really think you ought to try using a bit more saturated colours and contrast, take a look at PPDs edit, he keeps the white fabric low sat, but does the reverse on the blue details -really makes it pop and more interesting with the higher contrast too. Yours sort of looks very uninteresting and less bold, also fades into the grey background that you have. I think you should experiment with a wider range of contrast, and saturated colours similar to PPD's edit since low saturation has sort of been a consistent thing from the threads you've made.
While Tori is right, I don't think you really need to make the shape of the body shine more through the garmets she is wearing, I think the long hair is already suggesting enough of her being a girl IMO
