Continuous Carousel mode with uneven images

I partially made it work: https://diegoledesmafotografia.com/ using:

img.flex-active-slide, li, li.flex-active-slide {
max-height:450px !important;
width:auto !important
}

But:
1. I get an empty white space after the last slide.
2. The first slide does not show complete.
3. The slider does not scale up 100% as it used to for big screens.

Please advice.

Thanks.
