The blurry or wavy lines that outline artworks make them look like amateur graphics. If you are a professional or want to become one, you certainly want your vector artwork to look neat and sharp. To smooth out vector artworks, you need to blur the edges or to retrace them. You can use the Gaussian blur with GIMP and Adobe Photoshop. You can also use the "Smooth" tool with Adobe Illustrator and the "Node Editor" with Inkscape.
