Penguin NW - Final refinement 2

Another final refinement post is now needed because I have decided that I did not want to go against the template provided by penguin as looking at past winners none of them have changed the barcodes etc and have overcome the problem by adding a white box or something that contrasts well. 

I think that now the white box is present at the bottom, the text on the back would look better if moved up to start where the title does. The spine also needed adjusting so that there was a better balance between all of the elements on the front and back, but also remembering that it is a stand alone once the book is folded over. I placed the main title centrally between the Vintage logo and the authors name.
