>>1739072Thickness is surprisingly not bad in the hair. However, there are issues elsewhere.
For the eyes, use the circle tool, otherwise, the eyes look really lumpy. Don't use strokes for the blush lines. Make actual fills for them.
Don't have the face line connect to the hair line on the right side of the face as it makes no sense. Make it like the original where the hair is a separate shape, and it looks like the face line goes under the hair. The mouth thickness is unequal, so make it more consistent. Use sharp points for the eyebrows and the neck line. Have the line representing her right shoulder bend inwards, otherwise, it looks like the should should extend more and that it is missing from the image.
The main bow should be redrawn. Thickness is inconsistent, and the way you drew the bow is very flat. You want to show emphasis on folds, so you need to use more nodes to curve the shapes. You also need to draw the small middle fold as if it goes over the line, and the the rest of the bow going under that fold.
You have some color peeking for the hair by her left shoulder, and her left shoulder goes form thick to thin and should be consistent.
