他的写生作品虽然画起来较快，但笔笔实在，几乎每一张都是完整的作品，但是他没有止步于这些现场感强烈、充满生命状态的鲜活的作品，因为这些作品受限于户外作画时间和其他条件，幅面有限。但当这样的作品多了以后，他又变成工作室大制作的一种素材、准备，甚至某个局部的练习。他全国美展的金奖作品《亮宝节上的人们》，就是在大量写生作品基础上的大制作。我们看他不少藏族人物写生，非常完整，非常深入，是很精彩的单幅水彩人物作品，但当你把这两类作品联系起来看，惊叹于他大幅主题人物画作品的精湛艺术水准时，可以从这些单个的写生人物作品中找到原因。所以他的写生作品，既是写生，同时又超越写生。

许海刚为了感受、体悟大自然、不同地域的人文风情美，不辞辛劳，不顾生活习惯和气候条件的限制，用生命去感受体验树木花鸟、水泽高原，用心灵和不同地方的人民交流沟通。如他为了画好西藏题材，多次在西藏地区的高原过春节，熟悉那里壮美的高山草原以及淳朴的民风民情，所以他笔下的大地——山川河流、树木花草、人文风情、勤劳人民。体现了大地的厚重、生命的丰饶。形成了不同地区各美其美的大美图像世界，既是对大自然中各种生命形态的理解思考，也是对万物生命与自然交汇交融的心灵上的感悟。

Although his sketching works are quick to draw, the strokes are realistic, and almost every piece is a complete work. However, he did not stop at these vivid works with a strong sense of scene and full of life, because these works are limited by outdoor painting time and other conditions, and the format is limited. But when such works become more and more, he becomes a kind of material, preparation, and even a local practice for the studio's large-scale production. The gold medal work of his National art exhibition "People at the Liangbao Festival" is a large-scale production based on a large number of sketching works. We see many of his Tibetan figures sketched, very complete, very in-depth, is a very wonderful single watercolor figure works, but when you look at these two types of works together, marveling at the exquisite artistic level of his large-scale theme figure paintings, you can find the reason from these individual sketched figure works. Therefore, his sketching works are not only sketching, but also beyond sketching.

In order to feel and understand nature and the beauty of human customs in different regions, Xu Haigang works tirelessly, regardless of the restrictions of living habits and climatic conditions, and uses his life to experience trees, flowers and birds, water and water plateaus, and communicates with people in different places with his heart. For example, in order to paint Tibetan themes well, he spent the Spring Festival in the Tibetan plateau many times, and was familiar with the magnificent alpine grasslands and the simple folk customs and feelings there, so the land under his painting - mountains and rivers, trees and flowers, cultural customs, and hard-working people. It embodies the heaviness of the earth and the richness of life. It forms a big beautiful image world of beauty in different regions, which is not only the understanding and thinking of various life forms in nature, but also the spiritual perception of the integration of all things life and nature.
