Remove Space/Adjust Margin on Twenty Twelve Front Page (Custom Child Theme)

Hello everyone! I’ve pretty much nailed out everything I like about my custom Twenty Twelve layout minus a specific gap on the front page. Please take a look at where I’m at (https://www.cannibillies.com). WARNING: This site has an image containing blood as it is for my upcoming independent horror film. Nothing too bad though. With that being said, I am looking to have that front page simple, using the “header image” as seen. No entry content will be visible underneath. I’m assuming that gap has something to do with the space I’ve decided not to use on the front page specifically. ALL other pages are looking good to me and don’t have that space right above the footer. Any suggestions are greatly appreciated! Thanks in advance!
