I used to play around in DeviantArt. There, I found one of my favourite illustration artist, NukeRooster. He is an artist who focused on painting creatures digitally. I am also a creature artist so I am fascinated on how he paints, the gestures and the textures on his creatures. He successfully caught every details that a creature should have, granting it a realistic kind of feeling. I am often inspired by his style of art and how he drew his creatures, not only the painting style but also helps me to learn on shapes of creatures. His creativity blew my mind when I saw his commission works at first sight. He would take commissions on designing creatures for the clients, at the end the creatures designed by him will be owned by the client. This commissions work like a pet shop. His creations are mind-blowing. He encouraged me to push even further to improve myself and someday, I hope to become someone as great as he is.
(He is inactive in dA now, I found that he is more active in Tumblr.)
