Dont use GIFs for a slideshow. Gifs are extremely resource-intensive, the fade animation between slides is noticeably choppy. You'd be better off exporting this as an MP4 inside the video tag that has autoplay and loop attributes. 1. the file size will be at least half, and 2. you won't get that chugging choppy low FPS look.
Perhaps break up the hero text into a headline and paragraph. It's a lot at once/in the same mass.
Your text on project detail pages does not contrast very well and could be an accessibility problem.
I agree with Vadim to add some hover styles so it's clear what is interactive.
Also I really despise "contact" links that are just mailto. It's not clear that's the action that will happen unless I pay attention to the browser tip in the lower bottom. Perhaps just put the email address itself so it's clearer or set up a contact form.
Likes: the gradient/ minimal aesthetic is nice.
Contact links replaced : )
Add some hover styles.
I'd suggest shortening your hero copy. It's a bit verbose, unfocused, and positions you almost as a 'jack of all trades.' Maybe also adding hover states for your project tiles. Also I'd make your colors a a lot more accessible. The contrast is very very poor currently, especially on project pages.
I swear I have seen that exact website before. It was even posted here on designernews.co. But I might be wrong. What it tells me though is that this is lacking ... well everything in my opinion.
But seriously, put hover styles on it.
It looks really awesome! Keep on going
