I created all the beaches in a city from scratch.

Nice job! It's not that hard to find where you worked if you include some text, it's here: https://www.osm.org/#map=17/41.44296/31.74970

Some tips:

• A rectangles should be rectangular. You can assume a football field or similar sport field has right angles, so you should draw it as a rectangle. There is a built in tool for that. In the iD editor you used, select the field, rightclick-> Square, or press the Q key on your keyboard. This is usually true for semi detached houses as well. People like to build rectangles.
• I think the place=locality tag on this thing is wrong: https://www.openstreetmap.org/way/1302651829 I can't figure out what is that from the aerial imagery, but locality in osm terminology is something different:

The place=locality tag is used to name an unpopulated location for which there is no extant feature to which the tag could be associated.

Maybe the translation is wrong in the editor for this item, I see you used Turkish language. If it's some kind of an empty plaza or paved place, use place=square (wiki) or highway=pedestrian + area=yes: a hard-surfaced, open pedestrian area: https://wiki.openstreetmap.org/wiki/Square

These are small problems, it's really nice, keep up the good work!

It's also recommended to reach out to the local community, they can help a lot. You can find your official channels on this site for any place of the World: https://openstreetmap.community/?map=36.94533,34.03161&zoom=5.52
