--- Comment #3 from Iwicki Artur fedora@svgames.pl --- One thing I haven't noticed earlier is that you're not packaging the licence text. You should include the licence (COPYING.txt) using the %license macro. You can read more here: https://fedoraproject.org/wiki/Packaging:LicensingGuidelines?rd=Packaging/Li...
You may also consider including some files as documentation (%doc macro). https://fedoraproject.org/wiki/Packaging:Guidelines#Documentation
Another thing that's good to do is doing a scratch koji build ("koji build --scratch") of your package and posting the result in this ticket. This way whoever is reviewing the package can be sure it will build properly in the Fedora build system.
Before you can get sponsored, you will also need to do some package reviews. This does not mean doing "full" reviews, just posting some comments. You should visit the review request queue once in a while, look for new requests, see if you can spot any mistakes and report them (or report that everything seems fine).
I do not have sponsor privileges, but I hope this few bits of advice will help you on your way.
