I don't want to speak for her, but Chikyboy, Harmonylight, and Nicole Taber have had these as their pfps for a while. Kiwi probobably would have complained if she wasn't good with it. It's okay, It's not rude. Also, Nicole Taber and I give her credit.
Tell him I really appreciate it lol. But yes, and this goes for everyone, please please credit me as the artist if you put my art anywhere. Art theft is very common and not fun.
