The theme is the independence of Indonesia, and I used the Canva platform to create this poster.

 The size of this poster is A4, and I used many fonts such as Anton, Brice Bold, Water Brush, and others.

 I also used an image of Monas because it is most associated with Indonesia, and I added an image of Mega Mendung, which is typical of Java island. 

For the background, I chose the colors red and white because they are the colors of the Indonesian flag.
