- I also noticed fonts... Each of them has their license. You embedded (used path instead of text tag) the font to svg so it could font license violation.... Be aware. The "matiz" font is in gray zone. "Ubuntu titling" font too. It is lgpl3 and if you create derivative of the font so you must make your derivative under the same license... Even fsf didn't decided how to properly treat derivatives of font so just embedding font can be derivative so be aware....
- When you click on "more info", you open metadata of the project. The links to the profile page of the author is always there so you shouldn't add copy of it to the metadata trough additional links..
