Hello Wamia Zaman and welcome to OpenStreetMap!
One thing that'd be really helpful would be if you would use descriptive changeset comments that explain to other mappers what you're changing.
"#hotosm-project-16289 #OSM_Guatemala #Quetzaltenango #Kaart" is just a bunch of gibberish hashtags that don't actually mean anything, but something like "added some buildings in Guatemala based on (whatever) and (whatever)" would.

Best Regards,
Andy
