I like the fading image overlay effect but it may be a bit much because there’s no way to ‘avoid’ it. You’ll notice it doesn’t work on the right top of the left image (and vice versa) by the way because the padding-margin of the above elements is partly on top. Might be worth giving the images a higher z-index.
I see them in several places but what I described (the minor glitch) concerns the two large images on the main page. When you hover those at the top, the effect won’t work because the element above is overlapping them.
Also, I love the photography. One idea for keeping them consistently styled on an ongoing basis (not that they are inconsistent now) is to use a background blend mode:
