The highway here is NOT residential: it connects settlements. Residential roads are only typically found in urban environments/larger settlements. It should therefore be mapped as an unclassified road or a path depending on its ability to accomodate two tracked vehicles. 

Some of the round buildings are mapped with their shadow included. Use shadows as references to help you map (building footprints should be adjacent to shadows); do NOT include them in building footprints as this will result in mapped buildings being larger than in reality and in a more dence environment could obstruct other features.
