Hi!
Welcome to OSM!
As your first edit this changeset is  quite complicated and covers a very big area. Please create smaller changesets in the future. Additionally you drew overlapping, disconnected footways, without  taking into regards much what was already mapped before. 

I would ask you for the future to:
1) Create smaller changesets in smaller areas
2) Follow the warning/error hints your editor shows you
3) Integrate the existing OSM data into your edits
4) Connect new ways to existing ways
5) Connect new ways
6) Don't create overlapping ways
7) Don't create new parallel/overlapping footways in case there is no physical separation to the main road.

On the one hand the changes contain valuable information for walkability such as names and inclines. On the other hand the errors listed above  are quite severe and it is difficult to improve for me from the distance as a remote mapper. Please provide feedback here if you understand the issues addressed above and if you are willing to improve this edit.
