The Best Fanatic Sketch By a Friend

This sketch that I am posting might leave you in real confusion, that whats "Fanatic" about it??
The person who drew this was in a real good sprinting mood, was happy that she is going for a new beginning....leaving behind confused lines, relations, thoughts and emotions. She was changing her job!! her 1st job, may be she didn't like it, may be she liked it but it was obvious that she was happy about the future..

If we give a careful look it shows human head divided into four, which also can be a human heart, has thumping red at the bottom part and blues on the top that indicates "I am free, its a new day"............

There is a bit of black in the sketch as well randomly, seems the person had some intense, bewildering fear if this step was right??
