Hello JaidenV, welcome to OSM - looks like this is your first edit. I have corrected two things with your additions here.

First is the residential road off Heathley Park Drive. When there is a T at the end of the cul-de-sac you need to either use two ways (main road and across the end), or just use one way with either a straight end (ignoring the turning area) or an L shape. You added the road so that it went back on top of itself, which isn't how roads go!

Secondly to do with the residential area you added: it was on top of another residential area and used some nodes of other local features that should not be joined, such as the route of a disused railway. Please be careful to not overlap areas like this. (Also note that landuse=residential is usually a lot larger areas that those used on this estate, but a previous mapper has created smaller areas of houses here - it's always good to continue with what others have done in the area unless you are experienced and know that it is generally accepted to be wrong.)

Are you local to this area? You have made a few edits all around the world - I recommend starting with a few small edits in areas near where you live and are knowledgable about the local area and learn from there. Please join a local mailing list and ask for help if you are not sure!
