Some of the changes that I made to the School Safety Posters was that I changed the background and how it was formatted.  Instead of a grey background, I tried to go for a rough, greenish, background and instead of the lighting bolts, I used fireballs in order for the fire drill.  I went with the same colors as black, yellow-green, and red.  I used these changes in order to make the message really pop out to the people reading this with making the texts bigger, using more pop out colors, and formatting it in an easier way to read.
