In this version I used the words 'Your Right' as its their right to an education that has been taken away. It may hit home to more viewers as it addresses them and their rights.
Here I made the poster look more simple by making it look like a silhouette image (inverted colours) and by using only three colours. I used orange for the text to make it stand out more.
This is basically the same poster as the ones above but I used the word 'Education' on the balloon. Just to see wat words worked best.
This poster is the same as the black one above but instead I used the word 'Education' in the balloon.
