Background on homepage

Hi!

I changed my website to a static homepage http://tabathamorrow.com/

I don’t like the bit of white on the page. I tried using a posts slider, but it displays between the menu and above the header image. Is there a way to get it on the page below the image?

If not, just being able to change the background color/image on the homepage only would please me. I tried getting a plugin for that, but it didn’t work.

Mainly, I want to get rid of the bit of white below the header image on the homepage.

Any help is appreciated. Thank you. I’m using evolve plus.
