Hi, and welcome to OpenStreetMap! Since you requested a review, I looked over your changes here. Looks great overall! One minor thing to keep in mind is that some roads that aren't regularly used may be better classified as "service roads". I think residential roads are generally used to describe routes that multiple parties might use to access their homes, for example something leading to a cul de sac.
Let me know if you have any questions, and thanks for your contribution!
