Hi
You can override this code in custom css
.acm-features .mask-icon:after {
background-image: url(http://v1.bakrie.ac.id/images/logo/webp.net-resizeimage%205.png#joomlaImage://local-images/logo/webp.net-resizeimage%205.png?width=250&height=105);
border-radius: 50%;
content: "";
position: absolute;
left: 20px;
top: -20px;
height: 66px;
width: 60px;
z-index: 1;
opacity: .5;
}
customized above code to fit the image and change the image path with your image.
