Testimonial Carousel Slider with User Backgrounds

Design a testimonial carousel slider with user images as the background for each testimonial. The testimonial quotes should be prominently displayed above the image. Each slide will feature interactive call to action buttons, such as 'Watch Video' or 'Read More,' to encourage user engagement. The carousel should include navigation arrows for easy browsing, and display a total of six testimonials, with four testimonials shown in a row, spanning the full width of the component. The remaining two testimonials should be centrally aligned, creating a clean, balanced layout. The design should incorporate a vibrant color scheme to enhance visual appeal while maintaining a well organized and engaging presentation.
