Installed version doesnt look like demo

Hi Guys, Can I have some assistance please. I love LOVE the Verity free theme but after install, it doesnt look like the demo? Different images, font is larger and clunky. eg: on the home page the demo has the sleek "portfolio" title in allcaps and a small font, with great images underneath. I have a large 'Home' title with a wierd icon underneath and using different image with different sizing. Its just no the same theme. I have installed the Essential Content Types but not sure what to do now? Thanks in advance for your help
