cunning willow
This is the design of a sunglasses' collection called Miwani. I've first designed the hero section.
Below is the hero section of a sunglasses collection website.

I'd centre the title over the button, and centre both within the large white space. Left-aligned elements are great, but in this case the difference in length between the only two elements makes it feel less like they're left aligned and more like they're mis-aligned to centre. More elements, or a greater difference in width would make a left alignment more warranted.
The photo is very clearly and awkwardly cut off on the sides. You could either cut out some chunks or add extra pieces (which should be easy, especially on the left side) to make the photo terminate more elegantly.
I like the extra shapes you have behind the photo in the third page. It adds some playfulness and repeats the triangle motif of the sunglasses. I would extend those shapes past the photo, into the vast white space to make it less blocked off.
I wish that photo were higher resolution. If you're going to use this actual photo in production...
