Raven is a furry artist yes. but some of the stuff hes had
Now here's something funny, regarding the last image: It's a crop of the original picture, cropped just above the original watermark, with another watermark added in. "The Raven" is neither the artist's name, the commissioner's name, or the name of any of the characters in the picture. If your friend (implying I don't suspect "your friend" is actually you) is claiming this picture as his, I don't think it is, and I don't think he's an artist at all if he resorts to claiming other pictures as his.
