Hello Sir,
I have taken a look at your site it seems that your are using the "Source Sans Pro" font but on some pages the size of the Heading or Body text range from 16px to 21px which indeed looks a bit out of place. Also the way the images and background color is used doesn't reflect properly and doesn't keep the same "theme like" appearance you want.
I can re-design it for you and make your pages "match" perfectly.
This would be my first job here on Freelancer if you choose to have me, I will treat this job with utter professionalism and will deliver and even exceed your expectations.
Thank you for taking the time to read this, I hope you have a great day and looking forward to working with you.
Regards
