Moving from Pictures to Semi-Transparent Background

Half of my website is with images as the background such as these;

These pictures were hard to use behind the font I used for each of the page, so I decided to put in some semi-transparent backgrounds such as these;

These backgrounds are quite good in my opinion as they are still bright and eye-catching however the audience will be able to see the font better because of these backgrounds, I thought it would also be more fun to have different sorts of backgrounds as opposed to just one type of background as that is boring and the audience would be deterred.
