Erin Nicholls has always been artistic, leading her to study a number of creative subjects such as ceramics‚ metalsmithing & fine arts. She has done a lot of travelling since her childhood in country Victoria, living in a number of different cities and countries. In 2003, Nicholls lived in Florence, Italy, where she had private lessons in Old Masters' oil painting techniques from a master art restorer. In 2016, she completed a Bachelor of Arts Degree with Griffith University, majoring in Art History. Nicholls' style of art evolved from oil paintings to marker and pencil illustrations, which she has now been developing exclusively for three years. Her works are mostly realistic scenes, created in her unique style which is reminiscent of Studio Ghibli animation, as well as traditional Japanese woodblock prints.
In 2016, Nicholls took part in a group exhibition with RAW artists which featured her "Year in Japan" series. She then went on to produce another series set in Japan titled "A Night in Japan". In 2017, Nicholls was a top 20 finalist in the Bluethumb Art Prize with her marker and pencil work "Passing by Cherry Blossoms". In 2018, Nicholls won Best on Paper for the Bluethumb Art Prize for her work "Smoke", from her "Night in Japan" series. In 2019 Nicholls was a finalist in the Copic Award, with her piece "Red Light" being exhibited in Tokyo.
