First of all, I think why he can draw some free manuscripts at will, not because of his carelessness, but because of his design style. It's not hard to understand. Nowadays, many people in life may spend a lot of time making a commodity. Naturally, in its mind, this is not a commodity, but a work of art, but there are also many people who may get something of their own at will.
Secondly, I wonder why he can leave a deep impression with only a few strokes, because his works are very worth thinking about and must contain certain definitions here. I don't think a work that is clear at a glance is a good work. On the contrary, the creation that can help us think is a rare masterpiece. Designers' inspiration often depends on their imagination. What they imagine is always uncertain, so record their thoughts and sudden inspiration. Clothing rendering is a form of expression and recording. It is a normal process for designers to generate inspiration, quickly record and generate impromptu images.
Finally, although the works of the masters are very free and easy for everyone to see, I think they have very hard professional knowledge and working ability, which is beyond doubt. Not everyone can achieve this effect with a few pens. It is very likely that many people look really simple and think that they can achieve relative results. But when you find the masterpiece of this master in the whole process of the experiment, I will sell more than designing the scheme casually.
