Hello and Welcome to OpenStreetMap.
Could you explain what you're trying to achieve with Route1. Features in OSM should be verifiable, please see osm.wiki/Verifiability
Regards Bernard.

Hello and Welcome to OpenStreetMap.
Your water feature is a strange shape and extremely large to be on the roof. Even if the feature were inside it's not likely to be formally named "Water feature on roof".
Also, it is not a natural feature nor a pond.
Could you please verify this feature at the Hullabaloo Play and Party Centre or remove it.
There are sites other than OSM where fictional features can be made without disrupting a live worldwide database. I hope you can understand my concern.

Regards Bernard.

Hi thanks, that section now re-tagged to combined pedestrian/cycleway.

Hi, marking embankments thus it looks like all four lines are up on separate banks.

You could map two separate ways one on each side of the railway lines in different directions and tag them man_made=embankment (left-hand side of the way being the high side). Thus you will represent two slopes one on each side of the railway. Rather than eight slopes as at present.

If the above explanation is not understandable please just ask for clarification or look at embankment=*

Regards Bernard

Hello and Welcome to OpenStreetMap.
Your two new POI are identical and are positioned in the middle of the road. The apartment block is mapped so it would be best to properly add the numbers and address to the building outline.

I doubt the apartments are named Ferrier point nor are tourist features so ought to be removed.

Hi, that's good to know thanks, and very generous of the landowner.
I pass by here frequently on walks and always forget check out the phone box. Do you know if the red box is used for any specific purpose?
Regards Bernard

Hi, have the two section of cycleway east of the road (north and south of the bridge) been removed?

Hi, Welcome to OpenStreetMap.
I've removed the rest of the diverted path and added the new route.
Regards Bernard.

Hi, is the seat available for general public use? If not then perhaps private=yes ought be used.
Regards Bernard

Park and recreation ground tags removed, leisure,sport and surface tags amended to suit OSM practice.

Hi, I've marked the phone amenity as disused, as per OSM practice.

Hello and Welcome to OpenStreetMap.
Thanks for aqdding the name to the green. I've removed the tag landuse_1=park. The area is not a formal park, it's formally a green space. If it were a park then landuse_1 would not be the correct key anyway.
Regards Bernard.

Hello and Welcome to OpenStreetMap.
Nice work, you could map the boundary of the construction site, even roughly.
Please return when the construction is completed to fine tune your additions.
Regards Bernard.

Hi, OSM, a live world wide database is not really a place for personal notes. There are means to save your own POI without interrupting OSM. The POI are incorrectly tagged and positioned anyway. Thus they ought be removed.
If you need help with OSM please just ask.
Regards Bernard.

Hello and Welcome to OpenStreetMap.
The park is already mapped and named (it's not named Blackberries) so I've removed your POI but put a note on the park tagging.
Regards Bernard.

Hello and Welcome to OpenStreetMap.
I've amended the doctors tags to reflect the disused amenity. This in keeping with OSM practice. When the works are completed the new tagging can be added.
Regards Bernard

Hello and welcome to OpenStreetMap.
I've made minor adjustments to the address and opening hours to suit OSM practice.
Regards Bernard.

Hello and Welcome to OpenStreetMap.
Cornwall Road was first mapped in 2011 and amended several times since then. It's tagged as residential, private, 20mph road. Thus I've removed your new road as being a duplication. Please make any amendments you feel necessary to the existing way thereby keeping the ways history. If you need any help please just ask.
Regards Bernard.

Hi Welcome to OpenStreetMap.
I changed the city to Nottingham and capitalised one letter in the postcode. Also squared up the outline, otherwise all OK.
Thanks for your contribution, any problems please just ask for help.
Regards Bernard
