Question

a beautiful drawing on fuel conservation for first prize???

Answer 1

I'm not a good art critic but I can give you some idea.
You can search many pictures from internet but listen,dont exactly copy the picture.
Use your own creativity also,colour the drawing by dark to light tone and maintain your drawing page clean.
And friend,dont always hope for the first prize.
always remember, participation is more important than winning.

Answer 2

first of all you should try to make a 3d picture ,it is the easiest way to got first prize
