There is a dotted line down the center of the flower. That is what separates the side drawn by my left hand and the side drawn by my right. I had alot of fun doing this cause I drew both sides simultaneously.
I was bored so i learned to write with my left hand. I'm not that good yet but it obviously isn't that bad. Especially because I write really badly with my right hand. I really recommend that if you are bored and are about to bore your eyes out with a spoon, that you should become ambidextrous.
