Hello Benjamin, welcome to OpenStreetMap and thanks for contributing to the map in Ghana.
I can tell from your hashtags that you are part of KNUST YouthMappers.

I have a few remarks about your changeset:
1. I see that you have added arbitrary house numbers to the buildings. Please only add house numbers if you can see it added to a building. 
2. You have also added building:levels and roof:levels to some buildings wrongly. Do well to understand the tags you use before you use them. If you don't know explicitly what they stand for please avoid them.
3. You also changed building types and other tags. My comment for no.2 stands. Don't use tags and values you don't know.

Every Door app gives you freedom to use tags but as a beginner I recommend you use StreetComplete [1] so that you don't make such mistakes.

I've been here before as a beginner,  keep learning and keep mapping. Have a lovely day

Sam
