In Beijing illustration design training, many students will struggle to learn which illustration style. In fact, for a professional illustrator, both antique illustration and Japanese illustration are necessary skills. In addition, they also need to master the skills of ink illustration, magic style illustration, four-grid comics and so on. From the perspective of employment, Bian Xiao suggested that everyone should learn these painting styles. Nowadays, the commercial illustration course in Mars era contains a variety of painting styles, which can meet the production needs of different painting styles and have professional and comprehensive illustrator skills. After graduation, I can be competent as a commercial illustrator, animation designer, advertising illustrator and conceptual art designer.
