I just remembered. Do you have an OpenGameArt account? If not I recommend you to create one and also upload there your assets... OpenGameArt collects only free/libre assets but it is exactly what you make. Some people that use only free/libre assets don't visit itch because don't want to search for free assets inside a sea of proprietary assets. And it always good to have several sources of leads...
Itch allows to filter assets by license but if author didn't set correct metadata it is impossible :/
I want to improve the situation a bit because I believe that assets (and code) should be free/libre. It is a reason why I wrote you that first question about license :D
