Not to get too involved, though when I first joined this site, I don't know if I saw as much conflict as I'm seeing nowadays. We're all here because we're all Mario fans. In my unsolicited opinion, we all just need to learn to get along. That's going to take effort from people antagonizing and from people who just want the antagonists to stop. I get that we all want to see justice. If we're all going to get along, let's start by remembering what brought us together in the first place. The Super Mario series brings friends together. No need to let a few errors push us apart.
About the sprite sheet itself, it's nice work, definitely worth putting to use in fan games. All credit has been given where it is due and the results of the edits fit right into this revamped style.
