highway=pedestrian is normally for outdoor streets where vehicle use had been restricted
All of the shopping centres I've seen elsewhere in OSM are using paths, so I'll change these back.
P.S. there's quite a few OSM Notes in Aberdeen, so if you're able to survey and resolve any of them that'd be great (e.g. note/554758)

Hi, just wondering why you have changes these indoor footpaths into pedestrian streets?

Why have you added combined house numbers to the building when they are already on the outside of the building individually?

Looks good to me - thanks for the edit and welcome to OSM :)

Why did you turn this way in the middle of a river into a stream? way/325984154

Do you have a source for this paths you added? way/473077934
It looks suspiciously like you've just copied the Fife Council core paths map...

Well in this case I googled the village name + primary school and visited the website to confirm the name/location.
There's also the website https://schools.mapthe.uk/ (not working at the moment) which uses OS open data to add the polygon and name data.
Not sure I'd rely on people noticing there's no name - might be an idea to leave a note as well, asking if anyone knows the name?
Only thing for post offices is http://robert.mathmos.net/osm/postboxes/ - but as it says the data is © Royal Mail so only useful to guide you for surveys, or leaving notes.

Are you actually able to walk along this path? If so, what happens when you reach the A823 bridge?

While it's good you've removed the unnecessary name from the school, would it not be better to improve the map by adding the actual name?
You could have a look at http://robert.mathmos.net/osm/schools/progress/G/ for the name

Hi, welcome to OSM and thanks for editing the map.
Might be worth taking a look at: leisure=golf_course for suggested ways to tag the golf course features.
For example:
bunkers - golf=bunker and natural=sand
greens - landuse=grass, golf=green, name=
If you need any help let me know :)

Hi, you should probably add the actual name of the bowling club instead of just the generic name.
And also add historic=memorial to the war memorial node

Hi, saw you added layer=-1 to the cycle path and railway below the A801. Just to let you know that only one of the layers should be a bridge or tunnel - not both.
I've removed the tunnel from the cycle path and railway.

No idea sorry. I'd also mapped here from bing recently so just thought you might be able to help with speed limits/details if you'd surveyed :)

Hi, just wondering if you carried out a survey of this area?

Hi, welcome to OSM and thanks for the edit.
I have removed the residential area you created in Dundee as it is not correct.
If that area has concrete plans for houses then it should be landuse=brownfield.
Let me know if you need any help.

Hi, any idea what node/2466426757 is supposed to be?

You have changed these woods to parks for no good reason - these will be reverted.

Not sure if you've seen it before, but Strava has heatmap data which might help you identify and draw paths:

Hi welcome to OSM and thanks for the edit. I've removed the unconnected footpaths that you added.
For sidewalks that are attached to the road, you are probably better tagging them as sidewalk=left/right/both on the roads.
Also, if you do add paths in the future, make sure they are connected at one or both ends :)

Just wondering why you added the name "common" to these places you changed to parks? And also why you added amenity=public_building to a closed clinic?
