Organic Facial 2.0

Hey artists, have you ever gone through your drawings from time to time and realized you made some mistakes and wanted to correct them? Here is the second revision of my first digital drawing in April. This morning I was abit bored at work, so I used the mouse (yes the mouse, not the tablet!) to modify the color and his tongue abit. I know I did some mistakes with the anatomy at the first place but I can't fix it with my mouse, but at least the color makes it look better than before, yay?!

ps. I am working on several pieces hopefully can let you guys see soon
