Hi,  thanks for mapping. 

The buildings you mapped are well done as to their location. But pay attention to the squareness of the corners. Always draw buildings as square and precise as you can. Then add the Building feature type. And last, right click it and click the square icon. 

Also, please take care not to overlap neighboring buildings. In this changeset you "solved" the resulting warning given by iD Editor by adding  a layer tag. But instead you should retrace the affected buildings so that they do not overlap anymore.

Please watch these 2 short video for more info:

Thanks so much for your contribution, Martien, HOT validator.
