A clue

Six hours went by in a blink of an eye, and Ariana, who had been working without taking a pause finally got a chance to breathe when she went to examine Millie. 

When she arrived at the ward, she was stunned to see several round paper balls being thrown on the ground and as she got closer to the bed in the ward, she noticed the young woman sitting on the bed with a frown on her face. As she finished drawing, she suddenly stopped in frustration before tearing off the paper and throwing it on the ground. 

Ariana crouched down and picked up the paper that Millie threw on the floor and exclaimed in awe, "This is so beautiful." Even though there were slight flaws in the abstract artistic sketch of the woman on the paper, the art itself was beautiful as the eyes of the woman on the paper seemed to be alive. 

Millie's head turned to the direction where Ariana stood, and she shook her head before quietly saying, "My aunt is more beautiful."
