Hi, good edit. 

Since you've requested review one thing that could be done differently is continuing existing sidewalk way instead of adding a new one.

To do this use "shift" to select both the existing sidewalk and a node where it ends, then when you right click it, you should see an option to continue the way.

Since this sidewalk portion is new, it's also ok to add it separately so that other tags could be added (for example if old one is not as smooth as the new one and you'd like to map this)
