Sorry, I forgot to change the status back to 'good mapped' . With the other status I can send more info about improving mapping skills.

About your comment that a mapping becomes bigger.
The roofs of the buildings mapped here almost all have overhangs.

It is best to stay within the shadow lines while mapping. And, also of importance, zoom in to a minimum of 30 - 40 ft.
Best regards
