The Character Creator allows you to create your own sprites in SVG that you can edit in Adobe Illustrator or Inkscape. It's currently in development and I am open to suggestions for assets or features.

After so many years you still have not added any side views, back or kid versions. It is very limited on what someone can do with it.
Other views are available on demand. Plus I'll be updating every two weeks with new items for the next three months.
