cover mock ups

This was my first mock up of a cover page. i asked a peer to review this cover and this is what they said:
''There is alot of dead space on the page which could be filled with subheadings and other stories included with in the magazine to improve it.'
'The banner is also placed at the bottom of the page which doesnt stand out to the audience when they look at the magazine. To improve this you could try and experiment with the banner by placing it in different places which would make it stand out the the audience.'
