In the spirit of positive criticism, i want to say that your color work & strand texture are coming along very well! To improve, may i convey some experierence from classical painting? Please let me suggest that one begin by thinking of the hair not as strands, but as a mass, first, that has to be lit and so, like the body it adorns, has light, midtone, and shadow areas, apart from its texture. If you were drawing with pencil and paper, i would say to sketch a boxy version of the hair shape first, and refine the drawing later... but you get my drift. If you render a hair object without transparency mapping, you would see exactly this modeling. You know that the key light is falling from the upper left to the lower right, principally--you would know, you rendered her! So, the hair will have a highlight (i don't mean in the beauty parlor sense, but in the 3D sense :^)) on the top, and left. The midtones would fall around her crown and on the left side, and the shadow area would be in the lower right, furthest from the light. If some of it were blowing in back of her, it would catch the key light and be modeled similarly. Now, most detail and color is revealed in the lightest areas, along with the specular highlights. You will see less detail in the midtones; and the shadows should remain dark, thin, and mysterious. i recommend putting your texture-y work into those highlights & midtones, and leave the shaows alone, thus creating contrast and interest. You already understand color variation in the hair itself, and that strands float on the breeze and how it moves, generally, which is good--because that's hard to describe in words! Keep up the good work! i hope this helps! Please show us more as you go along!
