Adding cover lines

For the first front cover I have added some cover lines but need to decide which colour as the black isn't showing on the right side as well as it does on the left.

I am still undecided with which image I should use for my front cover so added some cover lines to it. The first picture works better because the second has lots of shade on the left side which makes the writing hard to read. However I prefer the second image more as it looks more symmetrical.
