I tried this on the slowest internet I could try(starbucks lol) and it loaded decently. I would try to optimize the photos and videos. I think you built this in framer, so be careful with layers and blurs and such as I have seen them increase load times. Especially since a lot of the blur use a bunch of layers to give a clean effect. I would say the testimonials section is a bit overwhelming for such a design being quite minimal. I would truncate or in some way shorten those in my own opinion. But overall, clean and pretty well optimized so far.
