>>1882036Pretty solid attempt, but here are some things:
1) You do want to work on thickness a bit. Pay attention to the distance between the two nodes at the V tips of hair, and make sure they stay consistent between the pieces of hair. Considering all of the hair ends as a two node square, make sure to keep the thickness consistent from one end to the other by keeping the nodes and handles parallel.
2) For the eyebrows and eyefolds, make sure to use fills and use a sharp nodes with independent handles. Also, draw those shapes as one fill that go over the lineart and coloring. Then make a clipping mask to hide it under the fills. This way you can maintain thickness and properly curve those shapes. For the major eyefold/eyelash below both eyes, draw most of it as one shape, except for the two eyelashes on the sides. Add those in after. You can Unite them later if you so desire. The highlights should all be above the lineart for the circle of the eye. Considering the image is darkened, you want those highlights to be darkened as well. Open the HSB scale and reduce the Brightness a little to make them darker. For the main coloring of the eye, color pick the inner (brighter) and outer (darker) coloring from the original. Then, select the fill and turn it into a radial gradient. Put the inner coloring as the brighter one, and the outer coloring as the darker one. Then adjust the handles so you can get an eye similar to the original.
3) For the nose, curve the tips in a certain direction, and thin them out more. When going from a sharp node with independent handles, you want to start off thin with it properly tapering off, to thick in the center, and then tapering off to the same kind of thickness at the other end. You should also convert the two middle nodes into smooth nodes to round it out more.
