Hello, and welcome to OpenStreetMap! It's always great to have people mapping their local surroundings.

I did notice that some of the shapes of the buildings were slightly strange - I recommend using the Maxar Premium imagery for mapping in Iceland, as it is usually more accurate and up to date. Comparing Bing and Maxar is also always a good idea, so you can see what's real and what's an artefact of the specific imagery being used.

Happy mapping!

Best regards,
