You're quite good at shading the bottom of long skirts. I agree and think the yellow and blond palettes should have a darker outline and a darker first colour. Here's the difference:
Also, I blended the blond and red with some shading. I took a midway colour (in this case, a desaturated, mid-light shade, redish-brown) and shaded between the red and blond so it blends.
Hope that helps. Pictures really are worth a thousand words. xD
I'm actually making a palette set soon, which you and everyone else will be welcome to use. It's amazing how much of a difference the palette makes! Now I can see that the shading on the boots is really well done, when I couldn't tell before due to the lack of contrast.
