Front Cover Editing

After asking others for their opinion on my front cover, I have come to the conclusion that in order to make my cover more conventional, I need to zoom in on the image in order to make my models face more prominent on the page and closer up and therefore she will be more eye catching and there will be less white/blank space. Having played around with this on my front cover, I have also found that, when zoomed in on, my image fits in to the rule of thirds much better which also makes it more conventional and aesthetically pleasing.
