I also did an exercise that I found on my instagram. About giving the character a back story. It helps you as a writer know how to write them. I have written characters sketches or quick paragraphs.
Sabastian, the Bird Whisperer.
Sabastian only had him and his mother Lily, and she was as beautiful as the flower with whitish-yellow hair and icy blue eyes. She was sweet and kind to everyone. However after Sabastian father died in war just several weeks before he was born she vowed to never love anyone else. She has her beautiful strong baby boy. He could whistle before he could talk. He could call of the local birds, and they would fly from all over to hear him sing to them.
When he was five when his mother died of a mysterious illness. However he still believed that she poisoned by an evil neighbor who would not take her hand in marriage. Since he was five years old he vowed to revenge the mysterious death of his mother.
He went deep into the forest and lived with an isolated monk who taught him how to live off the land. He would bring the birds for entertainment. On his 23rd birthday the monk died of old age. Sabastian knew he needed to move on taking his many birds as his allies.
Now he is seeking those who had killed his mother. . .
