>>1886869>The hair is a little strange due to the art and the frills aren't perfectThat's because you were working from a poor render of a poor vector trace of an image. Always use reverse image searching to find the original:
http://danbooru.donmai.us/posts/981343. You can see from the original that the hair and frills are much smoother. It will require some redrawing, but the areas are fairly simple to do, and the person who did the vector trace had to do the same thing, which is why some of the shapes look poor and odd.
For the hair, you have too many nodes in between the single node tips. Only use nodes at the single node tips, and adjust handles to curve the area in between. Only adjust the handles so much so that you can maintain curvature at the tips. If the area between could not be fulfilled following those parameters, add a node in between, but only then. For the smaller pieces of hair behind the main large fill of hair, do not try to do it all as one piece. Instead, do the large main fill first, and then add the smaller pieces behind it. This way you avoid having disconnected pieces of hair, and can keep those areas smooth. You can later unite all of the pieces of you so desire.
The skin is also much too saturated and brown, considering this character is fairly white in the anime. Colorpick the skin, and then adjust its coloring in the HSB scale, keeping it within these values: H: 25-35, S:15-24, B: 95-100.
