The header is great apart from the jujju.com text. Doesn't blend well. And yes, the theme doesnt suit well too. Get hold of a theme, or make one around the header.
The header image looks good but the theme is too simple and bit old too.Need a good looking one to impress visitors more..
I like the header design too, but dont like the template much, you should change it! Good Luck to you!
The whole site is in a white background, why dont you add more colors in your site? Also I would suggest you to post atleast one picture in each of your article. This helps if people are searching by images, you will get good results in traffic. If you compare a content with images and a content without images, most of the viewers will first be attracted to the content with image.
