Hi there, and welcome to OpenStreetMap! Your buildings look great, but there's just two points l wanted to discuss with you.

1: Square buildings. Use the orthogonalize tool (Q in JOSM, l think in iD too) to make all the corners 90° since most buildings have right angles. The areas of your buildings look great, just need squaring up.

2: Swimming pool area. The area you marked as "amenity=swimming_pool" should only include the actual swimming pool water. Please adjust this when possible.

Thank you & best regards,
