"Oil Painting Series"  is a collection of contemporay style artworks taken from Lily's practice on figurative, cubism, abstractive landscape and Still Life. They are Lily's another attempt to combine the Eastern and Western styles, the classic and contemporary  techniques. One of them was influenced by Sigmund Freud where she used the cubism techniques to depict three different layers of personality.《 油画系列》作品是叶丽又一次中西艺术融合的尝试。毕加索曾说过，“如果立体主义过渡是一门艺术，我相信，唯一能走出它是另一种形式的立体派。”  在弗洛伊德的理论中，本我、自我和超我是每一个人共有心理人格的三个层次。将弗洛伊德的心理学诠釋在立体主义的画面上，就有了《心理三维》。《天路》是源于画家本人对藏族舞的钟爱.《神秘峡谷》画面神秘、幽静，具有构成主义的形式语言，同时画面中还有种东方艺术的神秘蕴味感.
