How to improve the winning rate of science fiction painting?

The first is the basic problem of painting. Perfect composition, skillful technique, beautiful shape and good colors. Although the problem of creativity is science fiction painting, it should reflect the interests of the country and people, patriotism and national progress. Science fiction doesn't want to be random, based on reality, beyond reality, and wants to develop healthy and green technologies, such as interstellar migration and space exploration (judges love to draw national flags on spacecraft). Have their own unique creativity and expressiveness, and basically can win prizes.
