Your RP's are serviceable considering you're new and don't really know how any of this works yet. If you do continue to use Rosalina and Mario, I agree with the other people in the thread. Try a different take on Mario and Rosalina. Trust me as someone who tried to make Shinsuke Nakamura into a character here: using a premade good guy character is storytelling poison that usually ends up being boring. It also comes across autistic as hell, where it feels like you aren't really making an effort to work with the rest of the people here. I say that because I'm autistic, and as mentioned earlier, my attempts didn't work too well.
