I want to tell you very sincerely that there is no quick fix for painting. But in order to take the exam, there are some ways to cope with it, which may be what you want.
First of all, there is nothing wrong with your teacher asking you to copy. This is the only "shortcut" in painting. Your copying has no effect because you have not realized the true meaning of copying. Or maybe there are too few paintings, and copying is like taking a math, physics, and chemistry exam and asking you to copy other people’s work. Does this make you think a little clearer? Asking you to copy more is actually asking you to "memorize" how someone painted certain parts or what colors were used in which parts. I recommend you a copying method (it is just for exams, and may not be helpful for improving real painting skills). , you should first choose several model paintings (the ones of your favorite style or those recommended by your teacher). Find one with a frontal angle of the character, one with a 45-degree angle, and another with a side view. The reason for choosing paintings in this way is that during the exam, you are only faced with these large angles, and then you start to copy the model paintings from these angles like memorizing a textbook, trying to be able to draw them while carrying them! ! I am proficient in memorizing each of the three major angles I mentioned above! Then you go back to sketching. At this time, you should sort out the memories of the previous copying in front of the model, and then start to draw. Don't follow the model completely, but draw based on your own summary of the copying! You must use your brain more!
Introducing some small tips (still just to cope with the exam, not a real way to improve painting) to improve the effect of the sketched avatar: when dealing with the overall tone of the face, draw it a little grayer , and then draw the facial features darker (such as the eye sockets, the bottom of the nose, the upper lip and cleft lip, and the dark parts of the hair) to create a sharp contrast.
In terms of color, it is the same as the sketch I mentioned above. First copy more, and then try to memorize it. In terms of painting, it is still necessary to use more large brush strokes and large color blocks to shape the shape, and be more neat, so as not to make the painting look like ink. Color needs a sense of rhythm, and you must pay attention to the relationship between cold and warm! Usually the situation is like this: dark parts are cooler than bright parts, distant objects are cooler than nearby objects,,,, generally speaking, it is warmer near and colder at far.
It is basically impossible to achieve quick success in painting in a short period of time. If you just want to cope with the exam, just do what I said above and work hard. In fact, this is asking you to "memorize" painting.
Finally, let’s talk about the steps-------Sketch: 1. Observation (this is very important, understand the model’s modeling characteristics, light source direction, etc.), 2. Large-scale (don’t stick to details), 3. Lay out the general light and dark relationship of the picture (don’t stick to the details at this time), 5 in-depth description (pick the main painting, don’t fill it with details everywhere), 6 finish the finishing work (the finishing work is also important, such as adjusting the overall light and dark relationship, the relationship between virtual and real, where There are waste lines that need to be wiped off, etc.).
The color is basically the same as the sketch. Observe carefully------draw the general shape and lay out the general color---go deep---finish it.
The above is about painting, and there are also cultural classes. I don’t know how you did in the cultural classes. For example, if you can barely get the certificate in the professional examination, but your cultural classes are indeed You are studying very well. This will not delay your art exams. Because many times, candidates who are good at drawing are not good at most of the cultural classes, so many students who are good at drawing fail to pass the exam. The admission principle of art colleges is that after passing both professional courses and cultural courses, students will be admitted from high to low according to the ranking of professional courses.
Wish you good luck
PS: ..... It took me a long time to type this, all because seeing your question reminded me of the time when I was a student. feeling. ,,Come on! ^_^
