Getting the same layout as the demo- CARBON Light

Hi, I read a some topics with the same question (basically) but I can’t figure out how to do it, but I think is very simple:

I want this look (https://otwthemes.com/demos/carbon-wp-light/) in my site (https://www.comercialnaturista.com)

I even get the images of the slideshow when download the theme so I actually expected that they give you a pre-design page with that layout, but apparently is not the case…Help anyone??

Thanks in advance
