This is a simple quick fix which just jazzes up your homepage without doing anything to make the load any slower, you will want to replace the background I list with your homepage image to have it mirror your image.
This minor set of custom CSS will give your page a more custom look, check out the image below of it on my site as an example.

.featured-categories-wrapper {
padding: 125px 0px 20px 0;
}
.hero-container {
width: 500px;
height: 333px;
position: relative;
background-position: bottom;
background-size: cover;
background: url(https://acabadotheme.com/wp-content/uploads/2019/08/Fast-As-Lightning.jpg);
box-shadow: 0px 50px 70px rgba(0,0,0,0.3),
0px 10px 10px rgba(0,0,0,0.1);
}
.hero-container::before {
content: "";
width: inherit;
height: 42%;
position: absolute;
bottom: -42%;
background: linear-gradient(to bottom, rgba(255,255,255,0.3),white);
z-index: 1;
}
.hero-container::after {
content: "";
background-image: inherit;
width: inherit;
height: 40%;
position: absolute;
bottom: -40%;
transform: scaleY(-1);
background-position: bottom;
background-size: cover;
opacity: 0.5;
}
One thing which impacts Acabado non-stop is the poor look of the images on the website, especially the homepage and featured post images.
Issue for many with the homepage blogroll and sidebar having bold and or italic text is due to the way Acabado pulls in the excerpt to be used.
One of the things which have driven people crazy with Acabado is the fact that WooCommerce won't load, it is near impossible to have an "on-site" storefront.
Acabado has a Hero Image which works well for a desktop view but it is cropped and unusable in mobile view for most, this method allows you to replace the image
