Hello! I was wondering, what exactly is appropriate credit for you? Would you like your email to be shown or this page? I'm asking this because you really do deserve a lot of credit with art like this!
Hello! Just put me as Artist in the credits section of your game/project. Something like: "Art: Vicente Nitti (vnitti) " should be fine. Credits in social media posts, like tweets, are not mandatory, however, it would be greatly apreciated :)
