Hopefully this is the right place, I'm not sure it is, if it isn't please point me in the right direction. I want to make 3d willow trees for my wedding decor, I found the outline for the shapes online, but when I try to convert the image into a cut file the edges are jagged instead of a smooth cut. I think its because the images are just too low quality. Can these be enhanced or does anyone have any suggestions on how I can make this happen? I've already searched for a svg file that's already made, but can't find one. I only need one of each leaf section, I don't need any of the trunk pieces.

Thanks in advance for any help. Here are the pictures. http://imgur.com/a/7AYEKDw
