Hi, and welcome to OpenStreetMap! Since you requested a review, I looked over your changes. Looks good, the only issue I see is that the road you added should be tagged highway=service, service=driveway. This tag combo is for private driveways that lead to one house.

highway=residential is for roads that give access to multiple houses, think the minor roads that meander through a neighborhood.

Anyway, thanks for your contribution, and welcome again! :)
