Hi!

1. Could I ask you to provide proper changeset comments? "change" doesn't really tell anyone anything. Ideally, some combination of why you made the edits, what you changed, and what your source was (e.g. survey, aerial imagery, etc.). When you save your changeset, you can also select "Sources" in the "Add fields" box, which will allow you to record your sources. See https://wiki.openstreetmap.org/wiki/Good_change
3. If you're interested in improving the alignment of roads or paths in the UK, you should look at using the OSMUK Cadastral Parcels layer https://osmuk.org/cadastral-parcels/ as this provides lines that are perfectly aligned, making it easier to align the aerial imagery (I tend to use walls/fences in housing estates for the alignment).
