Hello and Welcome to OpenStreetMap :)

thank your for your contribiution. I'd like to take this edit of yours (a changeset) to welcome you as a fellow mapper and to give you some helpful hints on how to map better. One of the usual ways of communicating is through these comments, so here goes:

In this changeset (cs) you edited things on more than one continent. This isn't very helpful and you can find the explanation here:
https://wiki.openstreetmap.org/wiki/Changeset#Geographical_size_of_changesets

Above link leads you to an article of the OpenStreetMap (OSM) wiki where the community writes down most of the "rules" to which we'd like to adhere since there's millions of people using this database every day.

At least one of the "landuse=residential" you added snapped to a street. This means it shares a point (or node) with the highway that borders the landuse. We try to avoid that.

In most of your changes to date you added missing buildings or changed the shape of existing buildings. To be hones: they look a bit crappy. BUT, there's an easy fix :)
After drawing a building you simply hit "Q" on your keyboard and the angels all get squared. Most buildings have pretty square angles so please do that.

In closing I'd like to leave you with a few helpful articles of the wiki and wish you happy mapping
