Photos for front cover

For the front cover I wanted to make the photos more interesting to draw attention to the magazine as students walk past. Therefore I experimented on Photoshop to give myself some idea how i could change them to make them more interesting

I like the black and white ones as this works well with the purple of the background. also, i like the one with the inverted colours, except I may have to alter it as this one may blend into the background and not be as interesting.
