Wider pictures of homepage

Site URL: https://lukaszfilipowski.com

Hi! my website is www.lukaszfilipowski.com
I have issue with size of pictures of home page in supply template.  Pics are small and don't fit site on the right. With the galleries I do not have a problem, so I think that with good CSS I can fix it with my homepage too. Please help me. 

Add to Design > Custom CSS

.full-width-homepage.collection-type-page.homepage #main {
    max-width: 100%;
}
