>>1538277Lots of things wrong. Your line consistency is all over the place. Again, I am NOT saying to make it uniform, but if you are going to make hair lines, they should all be the same thickness, not super-thick on the LEFT side and super thick on the RIGHT, then swap the next lock of hair.
Also, if you are going to do something with varying thicknesses, I suggest making clothing lines thickest (with some exceptions being like nylon, sheer or thin, tight fabrics) then skin, then hair is your thinnest type of line. Mechanical lines, like her headgear should be made thicker or thinner depending on the "delicacy" of the item. For example, I'll use a Katana: You would make the spine of the sword thicker to emphasize it is not made for slicking, while the edge of the blade that does the cutting would be really thin. If you look at a katana, you'd notice they have a noticeable area where the blade edge becomes a wedge and from that wedge, becomes the spine of the blade. Those should be lines in between the edge thickness and the spine.
Something similar helps if you think of things like hair, skin, accessories and clothing types (winter clothing or armor would be thick-lined while nylon stockings or small ribbons would be thin)
It also helps you to break up one thing from another better.
Another thing is things like buttons - since those are "machined" you can make them using stroked circles. I would also make sure to copy-paste one to another so they are uniform to each other (as buttons really should be).
You also have a lot of kinks in the lines - I'd go back and make sure your bezier levers make nice, flat lines going in both directions.
Hope this helps.
