I study architecture. We have been practicing hand-drawing for a long time, but there is still no progress. Who can tell me how to draw a good color?

Line is the key, and the basic requirement of line is small and straight. When you start painting, slow down, relax your wrist and drive the brush with your forearm. The line you draw is straight, but don't push too hard, it will be rigid.

Generally speaking, lines need to be practiced for two weeks, one hour a day.

Then I began to practice perspective, which is mentioned in general art books now. It depends on your talent. If you understand perspective, you can start to contact relatively simple monomers. It's best to start with China folk houses, because the lines of folk houses are relaxed and much simpler than modern buildings.

If you are coloring, you should practice monochrome first, master the contrast between light and dark, and then practice compound color, and watch more master's works to cultivate color vision.

PS: Architects had better not buy recycled interior design books. There is still a big gap between hand-painted interior design and hand-painted architecture.

If you don't know, you can ask.
