Hello dulky, and welcome to OpenStreetMap!
Someone asked you to use more descriptive changeset names, and you've used more words, but "changes and more specific information" doesn't really explain much more!
If you read https://wiki.openstreetmap.org/wiki/Pl:Dobre_komentarze_zestawu_zmian you'll see the sorts of things that make good changeset comments.
Best Regards,
Andy
