Hi Johnson, 

Welcome to OpenStreetMap and thanks for mapping. "Bing aerial imagery" is very out-of-date in most parts of Ghana, kindly use "Esri World Imagery" which seems to be more recent. You can always compare Bing/Esri to see which more recent before using either to add new data into OSM. 

Also zoom in enough to see existing objects before adding new ones to avoid overlapping and duplicate features.

Further more it's not necessary to add your name to the changeset comments. Find out about Good changeset comments at https://wiki.openstreetmap.org/wiki/Good_changeset_comments

If you have any further questions here are OSM Community channels => https://openstreetmap.community/?map=7.90109,-1.15841&zoom=5.00

Happy Mapping.
