OK. Your site looks pretty good on my end. The one ad goes under your IG feed is all, nothing to ruin the user experience. When I make the window small like I would see it on a phone, the ad pops in at a certain point while scrolling down so thats why I thought it wasnt responsive. Also, Your Instagram icon is not linked properly in your menu bar. The feed links to your proper Instagram url, but your menu bar icon is not.
Great site and topics BTW.
