Hello, Welcome to OpenStreetMap!  It is great to have you as part of our community of map enthusiasts.  

* You deleted a couple of roads, was this intentional?  What evidence is there that these roads do not exist.

* The name tag should be used for the actual name of the feature, not a description, like "house 1"

* You deleted a park that was represented as an area and replaced it with a point (node).

* Buildings should be digitized so that the corners form right angles (90 degrees) - unless of course in reality the buildings don't have right angled corners, such as would be the case with a circular or triangular building.

* In one case you deleted a road that had a name and replaced it with one that did not.

* You should not list yourself (Chuene) as the source.  OpenStreetMap automatically records your username when you make an edit, instead cite a source that you used that is acceptable to OpenStreetMap, this could include "survey" if you drove/walked/biked around and collected this data.
