Hi, and welcome to OpenStreetMap! Since you requested a review, I looked over your changes. There are some issues here - mainly descriptive names. That means we should only use the name tag for the official or common name of a feature. In this case, it looks like you're wanting to prevent people from accessing this area. My suggestion for that would be to use access tags to mark the roads as private. Looks like that's already done!
Let me know if you have any questions!
