We have made the codes to decrease the height of Featured Slider in desktop, tablet and mobile size screen according to your site. So please go to the Appearance > Customizer > Additional CSS and paste below custom css code:

.featured-slider.featured-slider-style-4 .post-img-wrap:before {
	padding-top: 35%;
	min-height: 550px;
}
@media (max-width: 767px) {
	.featured-slider.featured-slider-style-4 .post-img-wrap:before {
		min-height: 470px;
	}
}
@media (max-width: 575px) {
	.featured-slider.featured-slider-style-4 .post-img-wrap:before {
		min-height: 400px;
	}
}

Thank you
