>>1875604For future images, always try to find the original image first. You were working off a pretty poor vector trace of an original image, which makes the job more difficult.
You definitely seem to be using too many nodes, especially in the fingers, ribbon, and hair. Only place nodes at the endpoints and major curves, and then use the handles to try and fulfill a given area. If they can't, only then should you add a node in between. This is very important for fingers, since they tend to require more nodes to get the shape right, and to keep the finger smooth. For the fur of the cat ears, use the handles more at the tips to give the fur direction and more emphasis. You don't want those areas to be flat and straight.
You also have some color overlapping, with the face and the collar, and the hair and the fur on the cat ears. If you're doing this in Illustrator, use Smart Guides (Ctrl+U) to help snap layers together so they don't overlap.
Here is the .ai file to see node placements:
