Hi and welcome to OSM!
I've noticied this changeset because of the tag highway=crossing used on this way:
way/637255597
This tag should not be used on ways, only on nodes, see highway=crossing
You mapped some separate ways for cyclists and pedestrians here but these ways are not connected to the same roads as the major roads, for example there is no connection to Rua Edmond de Souza Melo
coming from
way/637253975
I am not a local, so I don't know if this is correct. Please double check all connections when you add a separate way, see also sidewalk=*

Sorry, forgot to mention that you should not use the name tag to describe things, e.g.
name=Passage vélo
You may use description=Passage vélo or note=Passage vélo
instead. The name tag should be used if the object has an individual name, like a road or a river or a restaurant.

Hi and welcome to OSM!
I see that you started to map crossings.
You added nodes with the tag highway=crossing (Good), but you used crossing=cycle. That is very unusual, please try to find a common value here:
osm.wiki/FR:Key:crossing
Also, when you draw a way that describes the crossing footway / cycleway, don't use highway=crossing for it, instead use highway=footway + footway=crossing.
In your case I would not draw this way at all, because sidewalks are not mapped as separate ways. See also
highway=crossing
and
sidewalk=*
Hope this helps, happy mapping!

Hi and welcome to OSM!
I found two roads with highway=unclassifay instead of highway=unclassified. Please watch out to correct this typo in your JOSM installation so that autocomplete doesn't use it.

Hi and welcome to OSM!
I've changed the tag highway=higway to highway=residential on these two roads. See also osm.wiki/Pl:Key:highway
What is the status of road Niwa?
way/121794745
Cześć i witaj w OSM!
Zmieniłem tag highway = higway na highway = residential na tych dwóch drogach. Zobacz także osm.wiki/Pl:Key:highway
Jaki jest stan drogi Niwa?
way/121794745

Hi! I've changed the unusual tag highway=closed:service to the usual disused:highway=service on
way/636994483
See also osm.wiki/Lifecycle_prefix
Would be good if you could add a note why the road is closed.

I've reverted this change, see changeset/63781129

I've reverted this now, see
changeset/63780997

I think only a few renderers use the tag area:highway, see also
osm.wiki/Proposed_features/area:highway#Rendering

You wouldn't be the first, see e.g.
https://github.com/gravitystorm/openstreetmap-carto/issues/180

You can find all bad ways using this overpass query:

Hi and welcome to OSM!
I've noticed this changeset because of the multipolygon relation with just one inner member:
relation/8833646
The inner way way/636204264
describes a very small area, so I think you created this accidentially, as well as the multipolygon relation itself. Ths can happen when you press Crtl+B in JOSM, the hotkey to create such a relation.Besides the edit looks good to me. I did not yet repair the above problems, please let me know if you need help with that.

Hi and welcome to OSM!
You added a lot of ways without any tag here. I think most of them describe buildings, so the tag should building=yes Please don't connect buildings with highways like here:
node/6001720836
If you want to add a node close to another way press Ctrl when clicking on the left mouse button.
Hope this helps, happy mapping!

Do you need help to revert the changes done?

Hi!
Du hast hier aus einem highway=service ein highway=parking_aisle gemacht.
Ich habe das korrigiert, siehe
changeset/63748087
Mit highway=service + service=parking_aisle sollten nur die Wege auf Parkplätzen erfaßt werden, die nicht auch der Zufahrt zum Gelände bzw. Gebäude dienen.
Bing scheint da auch noch einen weiteren Parkplatz zu zeigen. Kennst Du Dich vor Ort aus?

Hi!
I've noticed several self-intersecting ways in this area like this one:
way/635269971
Please watch out to avoid this. I've fixed some problems here:
changeset/63747824

I think I did not change it myself because the sat images seem to show that the road is already (partly) razed. You probably know better.

If a highway=residential is closed, the tag would be disused:highway=residential,
not highway=disused.

Diese Kreuzung sieht besser aus, aber stop_line gibt es noch immer ;-)
Du kannst die z.B. mit overpass finden:
