Looks great. Do you have a specific license?
Personally and commercially.
Even with how beautiful your "RPG Worlds" assets are it's good to see another "Rogue Fantasy" asset in the set.
César may have meant like the GameDevMarket license which basically allows royalty-free use the assets in commercial products as long as the assets are part of a product like a game or video and not re-sold as assets themselves.
Linking your asset pages to the appropriate license can eliminate a lot of uncertainty with potential customers. Common concerns:
Are the assets Royalty-free?
Can the assets be used in only one project per purchase or unlimited projects?
