I think, if it is a competition at or above the county level, it is better to draw new changes in the city or something. Although it is very old-fashioned, they just like it and are full of praise for the city and new life. They are very active.
If it is a school competition, draw a gardener and praise the teacher; Draw a happy family.
In short, as long as it is warm as new.
I study art, and I know what their teachers like.
