签字笔在产生笔触的方面具有很大的局限性。因为它只能要么是画出粗细一致的线条，要么是一些点。而这幅原图在纹理和花纹上都比较丰富，其中，有软硬不一的布料、佩戴的金属腰刀、皮质的皮带等，还有虚实不一的阴影。图片上的这种丰富性和工具本身的局限性构成了矛盾，而这种矛盾就使得在绘画的过程中，如何以这个工具来体现这些质感成为了主要的问题之一。
Ballpoint pens are very limited in terms of producing rich strokes. Because it can only draw lines of consistent thickness or dots. The original picture is rich in texture and pattern, among which there are fabrics either soft or hard, copper handles of the knives, leather belts, etc., as well as shadows with hard or soft edges. The richness of the picture in textures contrasts interestingly with the chosen tool – the ballpoint pen – regarding its limitation being mentioned above. This makes that how to represent these textures with the ballpoint pen becomes one of the main questions in the process of this drawing.
在完成的画中，有两个地方是我觉得很有趣的。一个就是左边男性佩戴的腰刀在他身上的投影。由于这个投影的边缘线非常实，色度也很深，由签字笔画这个投在他身上的投影，和衬衣边缘形成的投影连成一片。这个连成一体的投影和旁边几处稍微浅淡一些、边线也没那么实的投影看起来似乎构成了一个在他的腹部的小风景画。第二点就是右边男性穿的外套由纵横交错的线条构成，而这种纵横交错的线条在视觉上造成了一种比较硬挺的质感，正好符合了原图中他身穿的那个西装外套的质感。
There are two areas I found interesting in the finished drawing. One is the shadow of the knife projected on the abdomen of the man on the left. Solid edge and dark shade, the shadow drawn by the ballpoint pen connected with the shadow cast by the edge of his shirt as one. With the several shadows nearby which are lighter and with softer edges, the connected shadow from the knife handle and the shirt’s edge seems to form a small landscape on this man’s abdomen. The second is that I used criss-cross lines for the suit jacket worn by the man on the right. The visual effect produced makes this jacket of relatively stiff quality, which matches the original picture.
下面的两张，一张是尝试加上了单色的水彩背景。另一张是尝试用碳铅笔来画。和签字笔相比较，碳铅笔能够制造出更加丰富的笔触和色调，具有很强的可塑性。不过签字笔在描绘细节上更具有优势。
Of the two drawings below, one is an attempt to add a monochrome watercolour background. The other one is trying to draw with a carbon pencil. Compared with ballpoint pens, carbon pencils are much more malleable and can produce much richer strokes and tones. However, it seems easier to use ballpoint pens (especially those ones with very fine points) to depict details.
