MEDIUM: Charcoal Art
SPECIALTY: ✔ Technical Skills 

Since Oliver has always been deeply inspired by a 20th Century master artist, Nicolai Fechin, Oliver employs his influence in creating sensitive, emotional and dramatic portraits in vine charcoal.

To capture the insight and warmth of each subject, then transfer it from life to drawing paper is Oliver’s motivation.

To leave behind an essence of personality on drawing paper, along with intense personal feelings, is Oliver’s attempt to reveal his approach to art and life.

After graduating in 1996, he started his art career as a computer game concept artist at LucasArts. From 2001 until now, Oliver has returned to his own school to be an art professor for the School of Fine Arts and 2D Animation. Oliver has been so drawn to art even as a little boy, he once recalled that he started drawing at the age of 3. Somehow, portraiture seems to be his favorite form of expression which he constantly practices, not only as an art professor but as a favorite hobby as well. Since 2011,

Oliver has been lucky enough to come across a few distinguished contemporary artists as his mentors, ZhaoMing Wu, Henry Yan, and Chung-Wei Chien. Their tireless guidance has urged him to put greater efforts into capturing fleeting human expressions and paying more attention to precise composition in figurative portraits.

Oliver’s first art book, “Drawing the Head for Artists” was published by Rockport publisher in the year 2019, the Spanish & Dutch versions are available in the year 2020. Oliver’s first educational step-by-step DVD, “Portrait Drawing Simplified” was published by Streamline Publishing in April 2022.
