In fact, the sketch exam of Shantou University of Arts and Crafts is not a very difficult problem. If you have a good foundation, it is not difficult. If you have a poor foundation, you have to work hard.

You can go to the teacher to teach.

It's best to learn sketch for two and a half years before taking the exam.

Also, I suggest you go to high school. You can also study art after graduating from high school.

I'm here to teach you a little.

There are actually several kinds of sketches. Like structure sketch. Structure sketch is the most basic in sketch. Light and shade are the most difficult to draw when sketching, because there are many stresses on drawing light and shade. When drawing light and shade, it is brightest, darkest and darkest at the turning point. Don't draw light and shade when you start sketching. Learn to draw light and shade after you have mastered structure sketch. The hardest thing to draw light and shade is to draw the back. If you are not careful, it will be painted black, so the whole painting will have no aesthetic feeling.

Sketch needs two majors. That is, professional thinking and professionalism.

I hope the above will help you.
