Simply fabulous. I have never seen a better portrait of an animal before. The fact that it was made only using paper and pen makes it all the more fantastic.
It's overwhelming! The colors are natural, fabulous and the textures are just explosive! It it just seems like you have drawn it hair by hair. And those eyes, they are totally off the charts. They just blew me away. The detail of the nose and snout is impeccable. And those whiskers, too. They are simply spectacular!
Indeed, I mistook this for a picture of a real tiger!
Keep it up!
