Hi! Right off the bat, I have no idea what you do because I just clicked the link. It took me a little bit of reading to know what you do. If your clients are coming to your site already knowing what you do, then I think it's fine. But if you're trying to get anyone and everyone to visit your site, I would recommend putting a brief summary/tagline of what your business does as the first thing you see when you visit the site!
Love the site! I think you could make the banner a little lighter, it's hard to see the background video and its beautiful! as for shadows, I think it looks really clean and simple, cohesive and professional as it is! Best of luck with your ministry 🙂
