Hi Joao, Thanks for all the edits that I have reviewed for you. This is one of the few that could be improved. Edit the building, click on the building and press Q which will make the angles 90 degrees and square. You can also make changes to the same area in the same changeset so you don't need to save all the time. Good luck and well done so far.
