Doodle Art using both of my Hands

When I was in high school; that was about 7 years ago. I've got an injury on the right hand. The injury is not that bad and I still could write something but I just realize that I could loss one of them and for that reason I started to train my other hand how to draw. I started with drawings and doodle and then I learn how to use it together with my other hands effectively. After months and months of training it then makes me easier to use both of my hands.
