I typically use a variety of photo references to get my anatomy correct, but I did not use any one particular image.
If you mean the character reference, he is my fursona, and the character design is owned by me - the reference I am providing was done by janscyther.deviantart.com - http://fc08.deviantart.net/fs71/f/2013/361/5/6/111___ventisia_by_dingoringo-d6zku6f.png
Did you use a reference for his piece? If so, could you provide it please?
You overdid it with the fur shading, that's the issue. Remeber every pixel is noise on the screen, too many different pixels make the piece this noisy. You could work with simpler shading, and keep the furry look on this.
