Kudos on the launching the site! You entered into well charted waters but that doesn't mean you don't have room to grow. Try to add features that can differentiate you from Instagram or Pinterest. There are some great suggestions here so don't ignore. Here few things I noticed; the website is cookie cutter WP site, so invest little in design and I think 99designs.com can help. Your site is about photographs and video on homepage threw me off right away as I thought it's video app; and video itself is not related to your product. See https://www.airbnb.com/, how relevant their video message is to their services. Don't get discouraged, pivot!!
