Feedback on my website (small business) + help with mobile view not loading properly

Hello community!
I'm launching a small business in the dance inspired movement for physical and mental wellbeing space. 

I've designed my website and I invite constructive criticism from the community. It's the first time I've designed a webpage: 
My website

Additionally, suddenly the mobile view of the website has stopped loading (it used to load up fine before I changed the design of one of the sections).
I wonder if the mobile view doesn't support a particular format or design layout. It's been difficult for me to pinpoint the root cause. Anyone with experience please do advise how to fix this problem. 

Thanks a lot everyone.
