Like that logo transition on scroll, but not really a fan of your white serif text overlay over the video. That should be executed differently. The choice of a serif typeface for all of the site content is also not a good practice. I would suggest to pick a nice and clean sans serif typeface for the content.

I dont't think that footer links are necessary, because you have a fixed menu. I miss some nice case studies of your projects and the overall layout structure doesn't seem consistent on all resolutions. That is really seen on the mobile view.

The services and the first page are almost the same. Maybe that could be merged into 1 page and you could make a further details page for your services.

That Quote Calculator seems like a interesting feature.

At first glance, this agency website would be nice until I scrolled down to the parts of the videos. 1) its distracting while I'm trying real hard to read the text. 2) the text is just hard to read.

For the portfolio page, aside from me seeing the actual site, I would like to know more about the project. But apparently, by clicking on the image it takes you to the site itself. Not good practice.
