That's the whole reason why I left Deviant Art. My photoshops almost never got any comments because my art wasn't some half naked anime cat girl. From that experience, I got discouraged from posting photoshops outside of the Newgrounds BBS.
Not to mention a lot of them are either ass kissers or complete snobs. No matter how bad your art is, the average commentor will praise it to no end. As for the snobs with a huge superiority complex for having page views in the tens of thousands, Deviant Art is full of them when there is drama of any sort.
After leaving Deviant Art, I came to appreciate Newgrounds more.
