Liu indeed disdained the rigid confines of the various schools of academic art, nor was he like most watercolorists, who strive for technical perfection. His work always displayed innocence and understated humor, the most precious qualities in art, for they spring from the uniqueness of the human soul.
的確，沒有學院派的嚴肅固執，也不像一般水彩畫家執著於完美技巧的演練，劉其偉的畫作總是流露一股天真與詼諧的氣質，而藝術最珍貴的，原本就是源自心靈的獨創。
