Hazel has the element of earth. She hopes to use her powers to become a better warrior.
A bit of context for the picture:
She was tasked with guarding the sheep. It was late afternoon, when she heard something in the woods nearby. She went to go chase the creature off, but ran into something much larger and fiercer than a fox or wolf. Knowing she can't defeat or scare it off on her own, she blocks it with tree roots and branches to slow it down. She runs back to her village to get help. Some of the villagers think she is a coward for running, but sheβd rather the village was safe and be called a coward, than in danger because she was in over her head.
